Process Types Supported by BW Background
Management
BW background management manages the BW processes that support background processing. For example, you can use BW background management to activate the data in a DataStore object in parallel in the background.
Table RSBATCHDEBUGTYPE contains the process types processed by BW background management. Some of the process types listed here are process types of process chains (table RSPROCESSTYPES) and some are special process types of BW background management for which there is no process type for process chains. Not all of the process types of process chains are handled by background management.
The process types supported by BW background processing are:

Background parallelization of initial BWA indexing |
Some of the processes in BW are still processed (in parallel) in dialog mode.
● RFC data transfer from the SAP source system to the PSA
● Activation of data in the DataStore object for the corresponding setting in BW background management (see below)
Some process types have special features when they are processed. These are noted in the following table:
Process Type |
Special Feature |
PSAPROCESS |
By default this process is processed serially. |
LOAD_NEWDS |
The parallelization setting can be made for loading from files. |
ODSACTIVAT ODSSID ODSREQUDEL |
● You can set parallel processing with dialog processes here. In the default setting, the processes are processed in the background. ● For these BW processes, table RSBATCHDEBUGTYPE defines maximum runtimes of one hour for the split off parallel work processes. The main process checks the split off processes at regular intervals. If it finds that a split off process runs longer than specified in the maximum runtime, the work process is stopped. In the runtime parameters of DataStore objects, you can define the maximum waiting time that the main process waits for the next free work process. This setting should not be longer than one hour.

Parallel Execution of BW Processes for More Than One Aggregate: AGGRFILL ATTRIBCHAN CHECKAGGR CONDAGGR ROLLUP |
Fill, roll up and change run each consist of several subprocesses, all of
which are processed in parallel. More information:
