BWABAP to copy aggregates from one cube to another

In COPA you have often a data model consisting of similar cubes but with different data.You can have e.g. a cube for data of the current year, another cube with data of the previous year and a last one with data older than 2 years. For good query performance you create aggregates. Because of the similarities between the cubes it would be nice to have a FM or ABAP that copies one aggregate from a cube to another cube. Better would be to copy all aggregates from the old to the new cubes. If you search in the repository and SDN, you will find report RSDDK_AGGRCOMP_COPY. This report copies one aggregate by its technical name or UID to the destination cube. So I played around with it and found some issues:

1. It hasn’t any value-help for cubes – I spent times to find an error, blamed to find out I entered the wrong technical name-
2. It doesn’t allow to copy all aggregates from source to the  target cube
3. Texts of the copied aggregate are different from the original
4. It terminates very hard and not user friendly if target infocube doesn’t exist

So I took a little of my time and made a copy of this report into customer namespace and added value helps for source and destination cube as well as to copy all aggregates of a cube to another. I also moved the checks for infocube existence at the beginning. Now the report ends with an error message in the output list window. 

The coding for the new report is now:
