To write data to SAP BW, you must complete configuration tasks on both the SAP and Informatica systems.
In the SAP system, create an InfoSource or DataSource based on the version of the SAP BW system that you want to write data to.
Assign the InfoSource or DataSource to an external logical system, that is, the Informatica system.
Activate the InfoSource or DataSource.
In Informatica Developer, create an SAP connection and use the connection to import an SAP BW Load data object. You can create an SAP BW Load data object based on an InfoSource or DataSource.
Create a data object write operation based on the SAP BW Load data object.
Define the write operation properties to determine how the Data Integration Service must write data to SAP BW.
Create a mapping with the write operation as the target.
Create a workflow based on the mapping.
Create an application based on the workflow and deploy the application to the Data Integration Service.
Create and start an SAP BW Service.
Configure an InfoPackage in SAP to write data to the InfoSource or DataSource.
Configure the Informatica system details under the third-party details in SAP. Enter the workflow name, application name, project name, and folder name. You can also use the command line utilities to define the third-party details in SAP.
Initiate the data load from SAP. You can either start the load immediately from SAP or schedule to run it a later time.
To schedule the data load, configure a process chain in SAP.
When you write data to SAP BW version 7.3 by using 7.x DataSources, the InfoPackage loads the data to the PSA. To load the data from the PSA to an SAP target, you must create a Data Transfer Process (DTP), and configure a process chain that links the InfoPackage and DTP.
