Configuring a Process Chain to Load Data

To load data into SAP BW, configure a process chain that links the following components:

InfoPackage process

Data Transfer Process

Additional loading processes

ZPMSENDSTATUS ABAP program

You need to insert a Data Transfer Process in the process chain only when you load to SAP BW version 7.3 by using 7.x DataSources.

The InfoPackage and loading processes process the data. The ABAP program sends status messages to the SAP BW Service. The SAP BW Service sends these messages to the Log Manager.

After inserting the ABAP program into the process chain, create a variant for the program. A variant is an SAP BW structure that contains parameter values that SAP BW passes during program execution.

When you load data to SAP BW 7.3 by using a 7.x DataSource, the transfer option is configured to load data to the PSA because the InfoPackage loads data only to the PSA.

When you load data by using 3.x data sources, use one of the following PSA transfer options:

PSA and then into Data Targets: Select this option when you want to store data in the PSA before you load the data to data targets such as an ODS, InfoCube, or InfoSource.
PSA and Data Targets in Parallel: Select this option when you want to load data to the PSA and data targets at the same time to achieve high performance.
Only PSA: Select this option when you want to load data only to the PSA. You can also select the Update Subsequently in Data Targets
option to load the data to data targets after you load the data to the PSA.
Data Targets Only: Select this option when you want to load data only to data targets such as ODS, InfoCube, or InfoSource.

For optimal performance, configure the transfer option to load data to the PSA. After the source system loads the PSA, you can update the InfoCubes in SAP BW.

The process chain might contain a single InfoPackage that loads data to the PSA only or to a data target only. Insert the ZPMSENDSTATUS ABAP program after the InfoPackage to send the status to the SAP BW Service.

The process chain can also contain an InfoPackage that loads data to the PSA and additional processes that load the data to data targets. Insert the ZPMSENDSTATUS ABAP program after each loading process to ensure that the SAP BW Service receives status information at each point in the process chain.

To configure a process chain and load data into SAP BW, perform the following steps:

Create the process chain and insert the start process.

Insert an InfoPackage process.

When you insert an InfoPackage process for a 7.x DataSource, the DTP associated with the 7.x DataSource is also inserted.

Insert the ZPMSENDSTATUS ABAP program.
