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:

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.

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:Loading Data into Aggregates Efficiently
