How can I use HANA Live Browser

SAP HANA Live Browser is a repository of HANA analytical views. The repository is based on SAP HANA Live standard and custom views.
It is a flexible tool to browse the definition of the views, data structure, and preview data on-line. You can also display data using SAP Lumira and Analysis for Office.
You can launch the repository by entering the following address: http://WebServerHost:80SAPHANAinstance/sap/hba/explorer/buser.html. If you are not sure what is the Web Server Host and SAP HANA instance, you can find it in using SAP HANA Modeler perspective in Eclipse (Properties > Path in the below picture).
One of the interesting features is the option to provide the access to business users. End users can display business data, models and structures according to assigned authorizations. Details regarding the installation of the tool you can find on the SAP HANA Documentation page.

SAP BI Analysis Authorization - required concept in BW 7.3x

SAP NetWeaver BW 7.3 brings a lot of new features. Some old concepts are also superseded by new ones. The 'old' reporting authorization is no longer supported by BW 7.3. You need to migrate to analysis authorization before upgrade. You also can't switch back to 'old' concept.

When upgrading to analysis authorization, the following Notes will help you:

      931898 Migration Analysis Authorizations
      938871 Migration Reporting Authorizations II
      1001652 (characteristic 0TCAKYFNM), 958665, 946724
      942799 and 944929 (RSECADMIN)

There is an interesting Expert Session on upgrading into BW 7.3, that covers authoriation topics.

What kind of problems did you faced during authorization swith? Please share with us your experiences!

Attributes Change Run - applying changes in aggregates

Basics of Attribute Change Run

Attributes Change Run applies changes into aggregates if there was a change in navigation attributes used in aggregates or in hierarchies of a characteristic.

This process in necessary, because in aggregates data from InfoCube are persistently stored in aggregated form (In InfoCube, no data related to navigation attributes or hierarchies are stored).

To start Attributes Change Run, go to:

RSA1, use menu Tools>Hierarchy/Attribute Changes.

You will see there a list of available sets of InfoObjects and appropriate change status.

If you mark a line, and click InfoObject List button, you will see a list of objects that are planned for that Change Run.

The second important button is Execute button. Use it when you already market the line, for which you would like to start Attribute Change Run.

Change Run process steps

  1. Change Run checks which characteristics and hierarchies had changes since the last change run. Run specifies which aggregates must be adjusted.
  2. Change Run apply changes (dialog process for each required InfoCubes' aggregates).
  3. Activation of changes in master data and hierarchies.

There is a SAP lock, that (during point 1) is preventing other changes runs to start a job for the same time. Also rollups and aggregate builds are not executed. The name of the lock: CHNGRUN_ST

The second SAP lock (CHANGERUN) is locking objects (InfoObjects, InfoCubes, hierarchies) that are involved in the adjustment (point 2).

When the work is finished, the CHANGERUN lock is removed.

There could be only one change run in the initial phase (1). If other change run starts, it will fail immediately. It is not possible to start multiple change runs. Read about parallel change run in SAP Note 534630.

Additional Notes:

Change Run process can be monitored, restarted using RSDDS_CHANGERUN_MONITOR ABAP report. You can start it using se38 transaction.

It is better to run CHR for all newly loaded master data in the process chain. Do not start it for each master data load.

How to insert two queries into one BEx Analyzer workbook.

I frequently need to use data form different InfoProviders. Sometimes, instead creating MultiProvider, it is faster to put two or more queries into one workbook and create separate tab to display joined data. Here are 7 steps to create such a solution:

1. Create queries you would like to join.
2. Open one of the queries in BEx Analyzer and save it as a workbook.
3. Create two additional tabs in the workbook, and give them names (e.g., query2, results)
4. Edit the query2 tab by adding design items: click BEx Analyzer > Design Toolbar > Insert Analysis Grid
5. Click on the Properties dialog box, change Data Provider's name and click create button.
6. Choose the second query and confirm your choice.
7. Create a table, on the result tab, that merge data form both queries. Save the workbook.

What about selection screen? The variables related to the queries will be displayed on one selection screen, if you use the same variable in the queries - there will be only one field for the shared variables.

To learn more about analysis grid, read Analysis Grid section at sap.help.com.

Search sites about SAP BW using customer search

I created Search sites on SAP BW and Reporting, my search engine, focused on searching sites about SAP BW, using Google Customer Search. It shows results mainly form the sites: help.sap.com, sdn.sap.com, bwarea.com, sap.ittoolbox.com (BW group), sapfans.com (BW forum). If you think it is helpful, interesting or ... worthless - give me your feedback.

SAP BW Process Chains - automation and job scheduling

Would you like to automate repetitive BW tasks like loading transaction data? Create Process Chains!

Let's begin with basic definitions:
  • Process chain (PC) is a sequence of processes linked together.
  • Each Process have a type (BW activity, e.g., activate ODS) and a variant (contains parameters).
  • Start process describes when the process will start (immediately, scheduled job, metaprocess, API).
  • Connector is linking processes; you can choose 1 of 3 options of starting next process: when previous finishes with success (green arrow), failure (red) or always start the next process (black).
  • Variant is a set of parameters passed to the process, such as the name of the InfoPackage to use for loading, the name of the InfoObject to perform a change run for.
Selected icon bar buttons:
  • Planning view enables to create and modify processes.
  • Checking view checks consistency of a process chain selected in plan view.
  • Log view shows log of the execution of a process chain selected in plan view.
Selected left panel buttons:
  • Process Chains displays process chains.
  • Process Types displays process types, enable to drag and drop process into main panel.

The picture below shows simple PC (loading transaction data into ODS and than into InfoCube).


Loading Hierarchy using Process Chain

Now, we will describe how to load a hierarchy into an InfoObject. The process will start every day at 1PM. The process chain will have the following processes:

Start >  Load Hierarchy > Save Hierarchy > Attr. Change Run

1. Start transaction RSPC and choose Process Chain > Create. Enter a name of the chain and description. You will be asked to insert a name of start process - choose New, enter a variant name and description.
2. Select Direct Scheduling option and click Change Selection. Click Date/Time, enter schedule start date and hour (current date, 01:00:00). Click Period values > Daily > Save > Save > Save > Back
3. Click Process Types button on the left panel. Expand Load process and click twice Execute InfoPackage. Choose the InfoPackage for the Hierarchy you would like to load and confirm the choice. To connect the Start process with the load process: right click on the Start, choose process > Connect with > Load Data > created process. 
4. Add processes to save hierarchy and attributes change run (commits changes in the InfoObject).
5. Save the process. Click Checking View button. If the chain is OK, activate and schedule the chain by clicking Activate and then Schedule buttons.

Additional information
  • To work with PC, you need authorization for authorization object S_RS_PC.
  • To monitor selected processes create a list of PCs using TCode RSPCM. This tool will enable you to see statuses of selected PCs and provide a link to process chains' log.
  • To have a PC that can be scheduled and maintained only in specified client - press Process Chain > Attributes > Editing Client, and enter the name of the selected client.
  • To transport client dependant PC with complete starting options, enter required background user data in the target system using TCode RSTPRFC.
  • If you transport PC with scheduling option: immediately the PC will start immediately after the transport.
  • To "stop" scheduled PC click Execution > Remove from Schedule.
  • To see overall PCs status - start BWCCMS tool.
  • PC can send e-mail message when process failed. To create e-mail alert right click on the process and choose Maintain Message option.
  • To see technical names and additional information about processes: click View > Detail View.
Examples of BW PC
Example of processes sequence when deleting overlapping requests form a InfoCube:
Start > Del. indexes > Load InfoCube > Delete Overlapping request > Gen. Indexes

Loading hierarchy, attributes and texts into InfoObjects:
Start > Load Attr. > Load Hierarchy > Save Hierarchy > Attr. Change Run > Load Texts
