SAP BW 74: few new features

The SAP BW 74 is available for some time already and I already posted few blogs about it. In this post I introduce two more functions introduced in this release.

1) New with SAP BW 7.4 SP8: XXL - Attributes
It provides a possibility to load and store different files types (so called Multipurpose Internet Mail Extensions (MIME) Types) or long string (data type STRING or XSTRING) as XXL attribute into BW. The MIME file format can be e.g. PDF, XML, office files, image, video or audio files. The XXL attributes are basically characteristics values lower or equal to 255 and long texts up to 1333 characters.
While specifying an InfoObject to store such a XXL attribute it must be set a new flag called “Supports XXL Attributes” which is available on Master Data/Texts tab of the IO maintenance screen. Afterwards on tab called “XXL Attributes” it is possible to specify which XXL attributes the IO should have.
See more information in online documentation.


2) History function – Within RSA1 t-code under Modeling section, there is a new view. It displays history of actions performed on BW objects. All actions with relation to workbench navigation on objects (e.g. display, change, manage etc.) are displayed there. Notice that all actions are grabbed as per same session of user. Actions which are captured there can be re-performed. It is useful function which helps within the navigation across the different objects in RSA1.


3) Source/target extraction possibilities on DTP – there are few new object types introduced from which a DTP can extract the data. These are Advanced DSO (aDSO), and InfoObject: XXL Attributes.

Similarly with regards of target object type of the DTP there are again these two new into which the DTP can store the data to.


4) New source system types – bellow are new types of source system introduced. These are mostly related to Operational Data Provisioning (ODP) source systems. See online documentation here.
ODP - BW
ODP - SAP (Extractors)
ODP - SAP HANA Information Views
ODP - SLT Queue
ODP - SAP Business ByDesign
ODP - Other Contexts

Possibilities of Process Chain monitoring

Monitoring of Process Chains (PC) is very important part of BW system administration. Basically only successful run of the PC guarantees that there is up to date data for BW reports. There are many different tools which can be used to monitor of the PC. In this blog post I will focus only on the tools that can be employed for automatic monitoring without manual interaction of administrator. In all cases described below an email with the status of the PC run is being sent out to dedicated user.

1. CCMS: tcode RSMON -> Monitors -> BI CCMS; The CCMS gives a list of the PC available in the system. If an distribution list together with message for process of the PC is created then the CCMS will sent an email as the PC’s alerts happens.

More information about whole setup can be found here.

2. tcode ALRTCATDEF – here an recipient list is created and together with alert settings for selected process chain failure is setup (in tcode RSPC -> menu Process Chain -> Attributes -> Alerting -> check an checkbox “Send Alerts if Error Occur”) then email notification is sent out. In this case the PC’s property needs to be changed for every PC to be monitored as settings's flag (alerting) needs to be checked.

More information about whole setup can be found here.

3. tcode RSPCM - simply particular PC needs to added and notification maintained. This case comes with less implementation effort. No chains will need to be transported.

Maintenance of user’s favorites in SAP NetWeaver Portal

SAP NetWeaver Portal is very common environment for accessing of BW Queries. Users have just one single point of access to the queries. It is very common for BW or Portal administrator to manage user’s favorites in Portal. Users have requirements to copy favorites from one user to other or to delete some reports from the user’s favorites. Here’s is how to perform such a tasks.

Copying of the favorites:

Login into the SAP NetWeaver Portal and then navigate into following path:

portal -> Content Administration -> KM Content -> root folder -> userhome


Now select the user which favorites are to be copied; go inside its folder and via context menu choose COPY:

Go to userhome -> and select the user to whom you want to copy the favorites to -> Click on favorites -> and then “OK”

Delete reports from the user’s favorites:
Similarly go into the folder of the user under path similar as above and via context menu delete the particular item which corresponds to the report that is supposed to be removed form user’s favorites.

"Field-based" modeling in BW

When it comes to effort for building of BW models, flows, objects or reports common perception is that developing in the BW takes long time due to many objects that need to be created in order to ensemble them into something which is working like report or flow. On top of this an transport management overhead comes as the objects developed in one system need to be transported into other system. SAP wants to address this and there are possibilities to “shorten” development time of the BW objects.

One of these attempts is so called "field-based" modeling. This type of processing is part of Layered Scalable Architecture ++ (LSA++) architecture.  What the field-based modeling means? By leveraging it; it is possible to integrate data into the BW with considerably lower effort comparing to classic BW development. The data for the models of the BW can resides outside of BW. Also the BW model can operate with the data on field level data without the need of defining InfoObjects. Moreover there is no need for having mapping of the fields to the InfoObjects. All this is possible by using new type of BW object – InfoProvider called Open ODS View. Starting with SAP BW 7.40 SP5 while creating new DSO there is a possibility to choose either the new DSO is based on the InfoObjects or on Fields. Also the Open ODS View can be defined of type “Database Table or View” and once it is employed in HAVA view it is fed by HANA table. Similarly we can use Advanced DSOs type of the DSO objects in BW 7.40 for the field-based modeling.

In closing words I would like to say that is nice to see that there are possibilities how to enable rapid modeling for BW. The field-based modeling together with BW Workspaces exactly supports this.

Doing SAP upgrade? What SAP Notes to check…

Depending on how complex particular SAP system is an upgrade experience can be very challenging. Therefore it is always better to check all information that may relate to the components that are going to be upgraded. The most important source of the upgrade information is SAP Notes. Within this blog post I want to show some strategies that use to when searching for the SAP Notes when collecting information for the upgrade projects.

Below are example of areas that are in my interests when I assessing the upgrade. Notice that everything must be based for particular version of components that is going to be upgraded. As an example further I assume that SAP Basis component (Software Component = SAP_BASIS) will be upgraded to version 7.5.

Note: I honestly do not think that my list is comprehensive however it may serve as starting point to anyone who is preparing the upgrade project.


Hangman.vbs

Hangman is one of SAP tools to analyze a hang situations on an SAP system. In order to be able to analyze this several types of information needs to be collected. The "Hangman" tool helps with that. It stores following information into a log file:

- SAP work process list of all application servers
- SQL Server process list
- Windows process list of all application servers
- Windows process list of the database server
- SQL Server database locks
- SQL Server configuration and log files
- extract from the SAP dev_* traces of all application servers

Log file generated by the Hangman can help to understand root cause of the problems with SAP instance. The tool supports both stacks (ABAP & JAVA) of NetWeaver. However main database type of the Hangman is MS SQL Server.
