Modification of Infoobject
I have modified the infoobject in APO BW.
Do I need to update rules and adjust to new structure ?
Thanks and Regards
As I understand it, you replaced one info object with other. Even if you have added and deleted, you need to modify the update rules. They automatically get deactivated. Also make sure that the changes you made(deletion and addition) are reflected in the infsource as well. You have to make sure that the mappings are all correct as you have deleted an info object, make sure that the mapping for this object is done with the other relevant object and any thing as such in mapping.
Simply the answer for your question is YES. You need to update your update rules and any abap logic involved.
Hope this helps. Please donot hesitate to ask any further details.
