Delete and recreate BWA index of a cube in process chain

Hello Guru's Image may be NSFW.
Clik here to view.

Got the following issue. Due to our model we have a selective deletion on one of our cubes every weekend. This cube is also loaded into the BWA.

For maintenance purposes we need a process chain which, after the selective deletion:

1. Deletes the active index on the BWA

2. Recreates the Index

3. Fill the index and activate it

I saw the following ABAP programs which might be applicable (also mentioned in other posts):

RSDDTREX_INDEX_DELETE                    Delete index

RSDDTREX_AGGREGATES_FILL           Fill the BIA index

But for recreating the index i'm lost:

RSDDTREX_ALL_INDEX_REBUILD - Deletes, Rebuilds and Then Fills All Active BIA Indexes in System

Is really too much ...

RSDDTREX_BIA_ACTIVATE_FILL         Activate and Fill BIA Indexes for Multiple InfoCubes

gives short dumps ...

Has anyone an idea of been struggling with the same issue?

Regards,

René
