Writing data into cube in delta mode

If there is a need to write data from ABAP code (e.g. from some UI technology like WebDynpro) there are a function modules like RSDRI_CUBE_WRITE_PACKAGE and RSDRI_CUBE_WRITE_PACKAGE_RFC to support that. The FMs are writing so called planning requests “Request w/o InfoPackage (APO Request)” means that particular cube needs to be set to transactional (real time) status.

It is not very well known fact that these function modules support also writing data in delta mode. By specifying input parameter called I_DELTA (to TRUE value), the system first calculates delta as difference between the data that is already present in the cube and data that is to be written into the cube. All characteristic tuples are evaluated of data set.

There are two prerequisites that must be fulfilled by the cube while using the delta function:

1. It works for cubes that contain cumulative key figures only and the cube is not a non-cumulative cube.

2. The delta feature must be permitted explicitly in the cube. It can be set on in the t-code in RSDCUBE. The flag “Delta Load Allowed with RSDRI” is stored in table RSDCUBE-DELTA_LOAD.

DTP reads different data than LISTCUBE

I came across a situation when DTP I created was pulling different data set comparing to t-code LISTCUBE. I wanted to validate data that the DTP was pulling as source for my custom ABAP login in BW transformation. To do this I opened t-code LISTCUBE and entered a same selection as my DTP’s filter was using. To my surprise, I got different data sets in the DTP and in the LISTCUBE. I started to debug the load and found out even more odd thing. In one of master data characteristics used in the source of the DTP, the data was not populated in none of the records pulled by the DTP. Whereas in the LISTCUBE the same characteristics the data was populated.

First thing that I tried was to run some tests for the affected characteristics in t-code RSRV. In particular, it was test called “Compare size of P tables/Q tables with X tables/Y tables” which can be found under All Elementary Tests -> Master Data. Error that was detected by this test was following:

15:00:06 o'clock on 17.03.2020: Start test run for user XXX
Compare sizes of P or Q and X or Y tables for characteristic RZZZ
Characteristic RZZZ: Consistency check between P and X, Q and Y tables
Characteristic RZZZ: Tables /BIC/PRZZZ, /BIC/XRZZZ are not consistent: 50.004 deviation(s)
15:00:06 on 17.03.2020: Test run for user XXX completed

From the error, it was obvious that I have inconsistencies between P (Master Data Table) and X (Attribute SID Table) table of master data characteristics (RZZZ). In fact, in the P table, there were records but there were no records in X table of the characteristics. I tried to use “Correct Error” function available in the RSTV t-code however; it was not possible to repair the error.  

Second thing I tired was ABAP program RSDMD_CHECKPRG_ALL. There are couple of tests available in this program. Most of them are available as well in the RSRV. As this program has also REPAIR function, I tried to apply it. 

However, I was again unsuccessful with it. The program when it ran on foreground dumped and while running on background there was following error:   

Message text                                                                                            
Error in BW:
Characteristic RZZZ: Checking all SID values in the X and Y table
Characteristic RZZZ: Checking table /BIC/XRZZZ
Characteristic RZZZ: Checking consistency between tables /BIC/XRZZZ and /BIC/PRZZZ
Characteristic RZZZ: Errors found during this test
Characteristic RZZZ: 1.403.304 values from table /BIC/PRZZZ do not exist in table /BIC/XRZZZ
Characteristic RZZZ: Following data records have errors (max 50 displayed):
             Characteristic RZZZ: Checking SID values for characteristic/attribute RZZZ

Question remained. How to fill X table - attribute SID table of the IO? In the t-code RSD1 – Characteristics maintenance there is one option. It is available via menu Extras ->Database Table -> Fill Attribute SID Table. While running this the X table was populated and tests in the RSRV or in the RSDMD_CHECKPRG_ALL report were positive w/o any issues. The functionality “Fill Attribute SID Table” available in RSD1 is also available via FM RSDRX_FILL_INITIAL_XYTABLE. Once all corrected my DTP was puling same data set as the LISTCUBE and data values in specific characteristics were not missing any more in the load.

20:35:34 o'clock on 17.03.2020: Start test run for user XXX

EPM add-in error: 500 Internal server error

While using EPM add-in in MS Excel there is, a quite common error called 500 Internal server error that may distract a users. It is appearing right away when the user just choose connection. Thus, the user even is not connected to BPC server.

As per error log (which looks like this - see below) there is no obvious reason for that error.

It is worth to check if there is a dump related to this error – in backend in t-code ST22. Normally there is the ABAP dump which may indicate what is root cause of the error. In this case, there is related to error in the hierarchy. In the details of the dump there is even BPC dimension tech name and hierarchy ID listed. The details like this lead to the error. In my case, I just needed to delete broken hierarchy.

Life after life of SAP NetWeaver and Business Suite/ECC

It was well known fact for some years now that SAP NetWeaver will be at some point reaching end of support. It is true for every software – at some point it is being replaced some something new and not being enhanced/maintained anymore. In the year 2017 the NetWeaver celebrated 20 years. However, SAP announced already earlier that end of mainstream maintenance will be on 31.12.2024 for version SAP NetWeaver 7.5. Similarly, for SAP NetWeaver 7.4 the date is set to 31.12.2020.
However, on 4.2.2020 SAP announced (via official update of maintenance roadmap) that they extended it to end of December 2027. In particular, for SAP NetWeaver 7.5 mainstream maintenance will be offered through 31.12.2027 and extended maintenance will be offered until end of 2030. Considering that by the year 2030 the NetWeaver will be death – it will be 33 years old if I count it correctly.

Concerning SAP Business Suite 7 – it will be also offered by mainstream maintenance until 31.12.2027 and extended maintenance until 31.12.2020. Nevertheless, there is a “but” like there always is. Mainstream maintenance will be provided for the latest three EhPs only after 1.1.2026. Another the “but” is that the extended maintenance comes with additional 2% fee on top of the respective support fee (20%). The 3rd “but” is that SAP customer needs to buy SAP S/4HANA license already to show that they are in process of transition to S/4HANA.
In October of 2014 SAP extended support from 2020 until 2025 for the ECC/Business Suite 7. At the end the most pressing question of all SAP customers – “Is there any chance that SAP will extend their 2025 deadline ECC/Business Suite 7“ has an answer,
For both NW and BS - after 1.1.2031 only customer-specific maintenance will be offered.

Finally, concerning S/4HANA current SAP’s commitment is until 2040.

DBSQL_SQL_ERROR error while writing to BW InfoProviders

I recently faced a strange error while working on simple BW transformation. There was an end routine in place. I had a few arithmetic operations within the end routine. In particular I was multiplying key figure by big number (10mil) – so called I was scaling up the key figure. The routine was syntactically correct. In addition, the transformation did not indicate any problems it was possible to activate it – so no problem in design time at all. On other had while in run time my load failed.
There were messages like following in the load’s monitor:

Runtime error while executing rule -> see long text
Update terminated in accordance with error handling setting
Overflow converting from '1.08647e+14'
An exception was raised
Error in substep
Data package processing terminated

There was also ABAP dump present, which was generated for the failed load in case target infoprovider was info cube.

Category               Installation Errors
Runtime Errors         DBSQL_SQL_ERROR
Except.                CX_SY_OPEN_SQL_DB
 Short Text
     SQL error "SQL code: 0" occurred while accessing table "/BIC/FZZZZ_ZZZ".
 What happened?
     Database error text: "SQL message: "
An exception has occurred which is explained in more detail below. The

"WRITE_ICFACT" "(FORM)", nor was it propagated by a RAISING clause.
Return value of the database layer: "SQL dbsl rc: 99"
>>>>>   INSERT (l_facttab) FROM TABLE g_t_bia.

In case target infoprovider was DSO object the ABAP dump looked like below:

Category               Installation Errors
Runtime Errors         DBSQL_SQL_ERROR
Except.                CX_SY_OPEN_SQL_DB
 Short Text
     SQL error "SQL code: 0" occurred while accessing table "/BIC/AZZZZ_ZZZ00".

     Database error text: "SQL message: "
An exception has occurred which is explained in more detail below. The

"INSERT_ODS" "(FORM)", nor was it propagated by a RAISING clause.
Return value of the database layer: "SQL dbsl rc: 99"
>>>>>   INSERT      /bic/azzzz_zzz00

I tried to comment out my arithmetic operations in the code of the transformation and the load succeeded. It was obvious that there is overflow going on while computing my arithmetic operation I was wondering why in the design time there is no error. My target variable of multiplying was type of DEC 21 Decimal 7 (e.g. IO /CPMB/SDATA in BPC) and that was not able to fit the result of computation that was bigger that DEC 21. When I changed my target variable to type of DEC 31 (e.g. IO /CPMB/LSDATA in BPC) it all worked fine.

In case there is no arithmetic operations in your code there might most likely issue with regarding parallelization. Some processing that are running in parallel are locking the objects (e.g. target infoprovider) that causes the error like this. In such a cases repair of DB object via t-code SE14 may help. Similarly, cube indexes rebuild via ABAP program SAP_INFOCUBE_INDEXES_REPAIR or in t-code RSRV may help. Another solution can be reduce maximum size of the data packages. All these things mentioned above are valid in case the BW is not on HANA DB.

Programs for migrating a BW systems

In SAP BW (as well as APO) systems, a report SAP_BW_MIGRATION exists. It contains help routines for different activities that are normally performed with the BW systems: migrating of BW systems between different DB or OS systems, system copies, UNICODE conversions, etc. In some BW systems similar report called NW_SAP_BW_MIGRATION can be available as well. Although the report was more important in older (pre-HANA DB) BW releases it is will available there.

Additionally there is a report RS_BW_PRE_MIGRATION which is focused on providing an information related to DB platform range partitioning. Result might be useful to identify potential issues relate to the partitioning.

Accelerated Application Delivery for SAP NetWeaver (AAD)

AAD (or sometimes known as AccAD) is so called soft appliance that reflects the physical landscape which it is applied to.

AccAD enables end users within organization worldwide to access web based SAP applications, (e.g. SAP NetWeaver Portal, CRM, etc.) at near LAN speed while overcoming bandwidth and latency issues. Techniques that are used to optimize the network traffic are caching, compression algorithms, and special application aware optimization. The application aware compression and caching mechanisms can be more efficient than generic WAN acceleration and application delivery technologies. It aims to accelerate global access to SAP applications but it is not a holistic application delivery tool for all kinds of traffic. Use cases for customer to use the AAD can be an intention to facilitate and speed up work with applications and file systems between central data centers and remote locations.

The AAD is here since approximately year 2005 and in today’s modern cloud based software solution it is probably obsolete. Currently there is a version 2.3, which has set end of mainstream maintenance on 31.12.2020.

BW transports: Transformation consistency check

BW transports are one of pain points in BW area. Many issues may popup during move of BW objects between SAP systems. I blogged about many of them already. This time I focus on topic of transporting BW transformations.

One issue that may occur with regards of transporting the BW transformations is that method execution phase of the transport does not save and activate the transformation. Instead, only warning messages are shown in the transport log. This the BW developer expects that the transport went fine but it reality it is other way round.

Similarly, same situation can happen in other scenario. In case system dependent transformations of the source system is not mapped or incorrectly mapped in table RSLOGSYSMAP then again only warning is present in the transport log

To solve this there is a RSADMIN parameter available to influence how the BW system shall react. The name of the parameter is RSTRAN_CONSISTENCY_CHECK. Below are values of the parameter that set the system behavior either to raise an error or warning in the transport log.

X = Error shown in the log and it forces the system to cancel the processing of the affected transformations
‘’ = Warning

SAP UI themes

Over the years SAP came with many themes for their UI technologies like SAP GUI, Web Dynpro for ABAP/Java, ITS (SAP GUI for HTML), BSP, HTMLb, BI, JSF, NetWeaver Business Client, Enterprise Portal, SAP UI5, SAP CRM UI and etc. In this blog post, I mention few of major ones.

First, there are two main categories of the SAP UI themes based on Unified Rendering (UR):

·        UR Classic = Unified Rendering Classic or UR 1.0
·        LS = Unified Rendering Lightspeed or UR 2.0

In general the UR is a SAP proprietary HTML rendering and JavaScript library for SAP UI technologies.

Frameworks (UI technologies) that use UR Classic are (at this point of time):
·        Web Dynpro ABAP (WDA-UR): SAP NetWeaver 7.00, SAP NetWeaver 7.10 
·        Web Dynpro Java (WDA-UR):  all SAP Netwaever releases out of maintenance ( <= SAP NetWeaver 7 EhP2 (7.02) )
·        Business Server Pages (BSP)
·        HTMLB for Java
·        SAP BEx Web Analyzer (Business Intelligence - BI)

Frameworks (UI technologies) that use UR are (at this point of time):
·        Web Dynpro ABAP (WDA-LS): >= SAP NetWeaver 7 EhP1, >= SAP NetWeaver 7.11
·        Web Dynpro Java (WDJ-LS): >= SAP NetWeaver 7.10)
·        SAPGUI for HTML (HTMLGUI-LS): ABAP kernel integrated ITS
·        Lightspeed Server Faces (LSF)

SAP GUI themes:
SAP Belize Theme – started in 2016, adopted Fiori 2 theme for classic applications
SAP Blue Crystal Theme – started in 2013 came with a new color scheme (blue and white), revised UI elements, revised SAP GUI icons, it was inspired by the Blue Crystal Design in SAP Fiori.

Conversion of basic cube into transactional (real time) one

 Once you create a basic cube in t-code RSA1 there is nothing within that t-code that would enable BW developer to change the cube to transactional (real time) one. However, there is an ABAP report, which supports such a conversion. It is called SAP_CONVERT_NORMAL_TRANS Conversion: Normal <--> Transactional InfoCube. The report also support backward conversion from transactional to basic (normal).

Here is brief overview of the report UI and its output:

Cube load failure call subroutine FILL_SID_CACHE

Some loads to BW cubes may fail with below error that is related to subroutine FILL_SID_CACHE.

An exception with the type CX_SY_DYN_CALL_ILLEGAL_TYPE occurred, but was neither handled locally, nor declared in a RAISING
The attempt to call the subroutine FILL_SID_CACHE in the program &PROGRAM& failed due to a type error involving parameter number
An exception with the type CX_SY_DYN_CALL_ILLEGAL_TYPE occurred, but was neither handled locally, nor declared in a RAISING
Error while updating to target XXXX_XXX (type INFOCUBE)
Data package 1 / 17.02.2020 20:40:29 / Status 'Processed with Errors'

There is SAP note 1972401, which describes this error.  Regeneration of data loads to the cube of the program happened automatically but call of the form routine went to the older version of the program. Therefore, it failed. Issue is most likely caused two possible reason. One can be buffering problem. Second can be that a loading process was already connected to the old version of the generated program.
As workaround, one can try to reactivate the corresponding DTP or involved TRFN and repeat the load. If it does not help use program RSDD_RSTMPLWIDTP_GEN_ALL with both check box ticked off for the BW cube that is affected.

More information:
1972401 - DTP failed due to Exception CX_SY_DYN_CALL_ILLEGAL_TYPE
2172882 - DTP execution failed with CX_SY_DYN_CALL_ILLEGAL_TYPE and FILL_SID_CACHE
