Process Types Supported by BW Background ManagementLocate this document in the navigation structure

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:

Process Type Description

AGGRFILL

Fill aggregates initially

ARCHIVE

Data archiving

ATTRIBCHAN

Attribute change run

BIAINDEX

Fill BWA indexes in process chain initially

BROADCAST

Process broadcast settings generally

CHECKAGGR

Check aggregates during roll up

CONDAGGR

Compress aggregates during roll up

CREA_HASHS

Compute hash values for scheduler tables

DTP_LOAD

Data transfer process

LOAD_NEWDS

Load with new DataSource (TLOGO RSDS)

MDHIERACT

Activate master data and hierarchies

MDP_DELETE

-

MDP_RSRV

-

MDWHERECHK

Master data check / Where used list

ODSACTIVAT

Activation of data in DataStore objects

ODSREQUDEL

Delete request from DataStore object / Rollback

ODSSID

Determine SID when activating data in DataStore object

PLSEQ

Process planning sequence

PSAPROCESS

Update PSA request in InfoProvider

REMODELING

Remodeling toolbox

ROLLUP

Roll up data in aggregate

SEARCHDEV

Search through developer trace

STATMAN

Build status manager fast access tables for InfoProvider

STATMANPSA

Build status manager fast access tables for PSA tables

TREXINDEX

Rebuild all BWA indexes

TREXINDEXP

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. More information:Runtime Parameters of DataStore Objects

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:Loading Data into Aggregates Efficiently
