Process chains having BPC processes executed only synchronously

In case of Process Chain that contains BPC related processes by default it doesn’t run a synchronously. Means if there are any parallel flows in the PC they just run one by one. Next one just starts when previous one is finished. This may look strange on first time as one would expect that parallel flow simply runs in parallel (asynchronously). But it has an explanation. As per below SAP Notes if PC triggered by BPC process chain '/CPMB/TRIGGER_BW_CHAIN' then no message is not sent out and whole PC is executed in synchronous mode.
The BPC processes that can be involved in such a PC can be anything that is dealing with objects using namespace '/CPMB/’.

To fix this and be able to run also the PCs with the BPC processes asynchronously below 1st Note must be implemented and parameter called 'TRIGGER_BW_CHAIN_ASYNC' must be set to X in BPC customizing.

t-code RS09 Transport Browser for BI (BW) Objects

With the regards to BW transports situation is not very easy for BW developers. Once you add objects that were edited or newly created into the transport it is not very easy to find out what objects are really in the transport. This is caused by fact that normally BW objects (e.g. query elements, TRFNs, DTPs, Ipacks, etc.) are represented in the transport by it technical ID which is not always possible to be read by humans.

Some of the BW developers came up with custom tool that basically associates BW technical ID with their descriptions to enable easier navigation with the transports.

However as of BW version 7.x there is a new SAP standard t-code that support BW transports. It is RS09 - Transport Browser for BI Objects. Corresponding program is called RSAWBN_REQ_TEST_TB and that one calls FM RSAWBN_REQ_SHOW_TB which handles all logic in the t-code. Nice thig about the t-code is that you can not only easily get to know what the objects in the transport are but also navigate to particular part of RSA1 t-code and start editing the object. This is possible via “Change” button.

What is strange to me is that SAP doesn’t really mention this t-code in the documentation. There are no mentions of the t-code what so ever in the neither at Also the ABAP name of the t-code has a TEST in its name. Similarly development package where the ABAP program is located is marked as depreciated. So perhaps this was some SAP internal development that was never supposed to be included into final versions of BW? Who knows?

Possibilities of DataSource replication

Replication of DataSources is quite painful in BW systems. It usually takes time and there is high effort that needs to be put into it. Normally it is done in tcode RSA1 -> Modeling -> Source Systems -> right click on particular systems and choose Replicate DataSources. This brings up below dialog box where parameters for replication can be set up.

By starting this up it activates all DataSource available in respective source system. SAP delivered improvement to this functionality via below SAP Note that supports replication of specific DataSouce within a source system or an application component.
Despite there are some drawbacks like it replicates all DataSources in 7.x fashion it speeds up whole replication process.

In order to be used this enhancement you need to setup a parameter called REPL_DATASOURCE_UI_740 = X in table RSADMIN. Feature is available as of BW 7.3 SP11 and BW 7.4 SP05.

Hierarchy activation syntax error

Recently I faced an error with regards to activate hierarchy related datasource. While trying to do that there was an error:

Syntax error in GP_ERR_RSAPTH3, row 30 (-> long text)

Issue is within data inconsistency for specific hierarchy in table ROOHIECAT. Luckily there are SAP Notes that can solve this issue. After implementing ABAP report ZROOHIECAT_REPAIR and running it for particular hierarchy issue is solved.

To get the ABAP report look for following SAP Notes:

484370 - Syntax error during activation of BW730 HIER data sources

Error loading data from BEx Query – so called VirtualProvider based load

Recently I faced following error. It was on BW on HANA system and source of the load was BEx (or as now called BW Query) Query.

Parallel processing of query 1 resulted in the following messages:
Error reading the data of InfoProvider ZCUBE1$X
Error 2,949 has occurred in the BWA/SAP HANA server

Parallel processing of query 2 resulted in the following messages:
Error reading the data of InfoProvider ZCUBE2$X
view or procedure invalidated;table or view name = 0BW:BIA:ZCUBE2/[Request Info: Object Name = "SAPXXX"."0BW:BIA:ZCUBE2", FM

Normally this should not be an error as having a BEx Query as source system is not an issue since BW 7.x. However this time even query wasn’t runnable. In attempt to run it I got message:

I tried to regenerate the query in in t-code RSRT but it didn’t help. Then I turned to SAP Notes search. I found a note 1656582 - Query terminations - InfoCubes, DSOs, master
Data in the SAP HANA DB. This Note suggests running ABAP rep RSDDB_LOGINDEX_CREATE for objects reported by the load error. It worked for me and after running it for both cubes reported I was able to successfully repeat the load.

The report offers to show XML output of all things that were recreated. Here’s how output message looks like:

BEx History not appearing in Query Designer Open dialog

Recently I observed that in my BEx Query Designer there is an empty list on History part of Open dialog pop up window. I knew that I opened many reports in the same BW system in past so it looked like that something doesn’t work. The dialog popup looked like this:

I checked and I found that personalization of BEx History is not active. To activate it is can be done in t-code RS_PERS_ACTIVATE which points to ABAP report of same name.
The t-code is also accessible via SPRO -> SAP NetWeaver -> Business Warehouse -> Settings for Reporting and Analysis -> General Settings for Reporting and Analysis -> Activate Personalization in BEx.

For me it looked like below:

After activating it it turned to this and I started to get a list of previously accessed reports in BEx QD:

The data of previously accessed reports is itself stored in DSO “Personalization Data for the BEx Open Dialog [0PERS_BOD]”. ABAP code which does the activation is encapsulated in ABAP class CL_RS_PERS_PHK and in particular in method ACTIVATE. Table RSPERSHEAD stores information whether BEx History is active or not.

Within the t-code among the BEx history if can also be activated values for BEx Variables that were selected and in case of Web applications report’s drilldowns are saved.

When process chain will run next time?

One quick tip today for SAP BW developers here. 

When we need to find out when process chain will run next time we normally turn to t-code RSA1 or RSPC1. While having the process chain displayed there is a button “Next Start” available in the toolbar. Clicking on the button there is a pop up window displayed with the information about date/time of the next start.

Now how to find out the same if I need this information in my ABAP program? Luckily there is a nice FM RSPC_GET_DELAY. Just by giving the process chain name as input parameter it displays next start of PC.

ABAP inline declaration doesn’t work in SAP BW

Since I started to use ABAP inline declarations I liked it much. Naturally I’m using it in all SAP NetWeaver environments where I do ABAP programming. However in case of SAP BW I recently faced problem applying the inline declarations.

In particular I programmed a Start routine within SAP BW’s transformation. I used the inline declarations in the Start routine. If I put the same code I had in the routine into standalone ABAP program - the code seemed to work. But if I placed the same code into the routine I got error message while trying to activate the transformation – “Error in Start Routine”.

The transformation couldn’t not be activated. I tried to do hopeless thing – to remove the inline declarations. So I redid the code w/o it. And surprisingly it worked!

The version of the SAP BW system I used was:

SAP_BW                  740     0009   SAPKW74009  SAP BW
SAP_ABA                 740     0009   SAPKA74009  Cross-Application Component
Kernel release          742
Compilation              AIX 1 6 00F79A484C00 use-pr20160324 Mar 30 20
Sup.Pkg lvl.             329
ABAP Load               1981
CUA load                 40

As the inline declarations are available in NW release 7.40, SP05 I assume it should work in SP09. However turned out that BW doesn’t really work with it. In case it is used standalone (e.g. ABAP report or FM) without encapsulating it into BW object like the transformation it doesn’t. I need to try to upgrade my system perhaps to BW 75 to see if it is solved in there :)

What is embedded BW?

There is an embedded version of BW available as of NetWeaver 7.0. This means for any SAP NetWeaver based system like ECC 6.0, CRM 7.0, SCM, Solution Manager including SAP Business Suite and S4/HANA there is a BW available inside.

Primarily the  embedded BW shall be used within scenarios that are implemented in host system (ECC, CRM etc.) like embedded reporting scenarios (by leveraging BW's Analytic Manager (OLAP engine)) or embedded planning processes (leveraging BW's planning engine) however it is still full blown BW system. As per SAP they do not advise to use it as enterprise data warehouse.
Below are restrictions that are given by SAP while using the embedded BW:

1. Amount of data - shall not exceed 20% of total data volume in the system. If this happens there is probably a negative impact on core system functions.

2. Licenses – you may require license to run embedded BW in your NetWeaver system.

3. Security - it uses different authorization concept (BW one over classic concept used in ECC)

How to enable the embedded BW? Couple of activities shall be done in order to make the embedded BW work. This includes:
Assign Logical System Client – table RSADMINA
Set BW Namespaces to Modifiable - /BI0/* and /BIC/*
Activation of technical content
Switch On Business Function

What foreign currency rate was used in BW currency conversion?

BW uses standard SAP’s ECC functionality with regards to foreign (FX) currency conversion. This means that same set of TCUR* tables are being used while the BW system is doing the conversion. This is valid while doing the FX conversion during transformation /loading of data and also while running reports.

In BW reporting a key figure in report can have Conversion Type specifies in its definition under Conversion tab in its properties. 

The Conversion Type that can be chosen here are defined in the SAP BW backend – in tcode RSCUR. Here all settings like: what and how an Exchange Rate shall be obtained; where a source and target currency shall came from; and Time Reference to which the conversion type shall be tied to are specified.

So this is all that can be setup for the FX conversion. While looking at the converted numbers in the report’s output an issue of wrong data can arise from users. Question here is basically what FX from table TCURR was used?

To find out that for starter an “Currency and Unit Conversion” debugging can be started form t-code RSRT. This is available by hitting on “Execute + Debug” button.

While debugging it can be seen that following function modules are used in following sequence:
RSW_CUR_TRANSLATION_RATE_GET   Wrapper function ->
-> RSW_CTT_GET                                  Reads currency translation type
-> RSW_SCUR_CHECK_AND_GET              Determine source currency
-> RSW_TCUR_CHECK_AND_GET              Determine target currency
-> RSW_TRANSLATION_DATE_GET  determines date used to find translation rate
-> RSW_RATE_GET_BASIC                              determine the translation rate
-> CONVERT_TO_FOREIGN_CURRENCY here function DATA_FROM_DATABASE is called which calls another function DATEN_BEREITSTELLEN and this one finally reads the FS rate from table TCURR for previously determined Currency conversion type; from/to currency, date and client of the SAP BW system.

Therefore you may want to just set a breakpoint into the FM CONVERT_TO_FOREIGN_CURRENCY to speed up debugging process.
Notice that variable DATC is nothing else just value from EXC_DATE variable converted into internal format by below ABAP statement:


This means the source variable in character format is converted into target one as complement on nine - difference to the number nine.
Needless to say that above statement is obsolete ABAP statement. It shall be replaced by using TRANSLATE statement.

Deleting error stack of DTP via ABAP

Error stack of DTP is function that is very useful in scenarios where data is not coming in proper format. While using it erroneous records are filtered out and only those which are correct are uploaded into data target. Later on BW administrator can correct the erroneous records and upload it too.

Below there is the error stack req ID 2.115.361 as depicted in DTP’s maintenance screen:

Now imagine that this error stack req is snot needed any more. We can also see it via ABAP report RSB_ANALYZE_ERRORLOG. The report provides a list of all available error stacks request in the system while analyzing contents of error tables:

To delete the error stack data of particular request we can use ABAP report: RSBM_ERRORLOG_DELETE while specifying particular DTP’s ID and ticking off “Delete Log” check box:

This is how output of RSBM_ERRORLOG_DELETE report looks like. After that the error stack req is not visible from RSB_ANALYZE_ERRORLOG either in t-code RSA1.

Printing to PDF from SAP GUI

In case you need to save an output from SAP GUI into PDF format there are couple of options.

First of all Spool functionality supports saving PDFs within t=codes related to spool request such as SP02. It is available under menu Spool requests -> Forward -> Export as PDF…

In case system is based on older versions of SAP NetWeaver there are couple of ABAP reports that can be used to convert any spool request to PDF such as: RSTXPDFT4.

At last there are few applications t-codes such as in SD module: VF03 (Display Invoice) in which by entering PDF! Into t-code field automatically generates the PDF file.

ABAP inline declarations

One of the new features of ABAP version 74 is inline declarations within ABAP expressions. The feature helps to shorten ABAP statements as there is no need for specific data variable creation upfront the statement.

The inline declaration is executed using an operator in a expression while placed in declaration position. Result of the inline declaration is used within the ABAP statement at the statement operand.


DATA(itab) = VALUE t_itab( ( ) ( ) ( ) ). 
LOOP AT itab INTO DATA(wa). 
DATA(text) = ’…’.


DATA(dref) = NEW t_itab( ( ) ( ) ( ) ). 








Method call:
oref->methIMPORTING p1 DATA(a1)
... ).
DATA(ref) = class=>factory( ... ).
DATA(ixml) = cl_ixml=>create( ).
DATA(stream_factory) = ixml->create_stream_factory( ).
DATA(document) = ixml->create_document( ). 

Target is work area:
  SELECT SINGLE @abap_true FROM /bic/pcompcod
WHERE /bic/pcompcod @i_compcod AND objvers 'A'
INTO @DATA(lv_compcode).
Target is internal table:
