Generating the Master Data Export DataSource 

Use

A DataSource is needed to transfer data from a source BW into a target BW.

You can generate an export DataSource for master data, and thus for individual InfoObjects. By doing this, all the metadata is created that is required to extract master data (all attributes, texts and hierarchies) from an InfoObject.

Prerequisites

The source BW must have been created and actively saved in the target BW as BW Source System-Defined. The steps to be carried out are the same as those when automatically creating an R/3 source system.

The data content of the data target is activated.

Functions

You can use the selected DataSource as a DataSource for another system. The relevant export DataSource is not displayed in the InfoSource tree of the source BW.

The metadata of an export DataSource is generated as it exists in the source BW. This also includes the procedure for external systems.

Activities

...

       1.      Select the InfoSource tree in the Administrator Workbench in the source BW.

       2.      Generate the export DataSource from the context menu of a master data InfoCube.

The technical name of the export DataSource is called

8******M. for attributes (M stands for 'master data')

8******T for texts.

8******H for hierarchies.

(The asterisks (*) stand for the source InfoObject.)

Therefore, when you create an InfoObject or a master data InfoSource in the source BW, please make sure that the length of the technical name of each object is no longer than 28 characters.
