Can we add a cube to BIA if the requests are deleted daily

Question

Hello gurus,
We are facing a question with what cubes should be the candidates for BIA.
We have few infocubes where the data is loaded for the current period daily and the previous request is deleted. This is how this cube handles the delta. Can we add this type of a cube to BIA without having to re-index the whole cube every day?
Most forums and experts say we need to re-index the cube once you delete data out of the cube selectively. Is this procedure considered selective deletion and does it not work like a regular delta and if we roll up BIA after the load, does the BIA automatically load the delta indexes?
Please let me know your views on this.
Thanks in advance.

Hi ,
Yes, you can do the rollup and it will take care of filling the indexes.
We have a similar scenario, where we are using "Delete Overlapping Request " for Budget and Target Data for few cubes. We have indexed the cubes and use rollup to fill the BWA Indexes in our daily process chains.So , i would suggest you that there is no harm in this process.
But over the time , depending on the data volume, you need to delete unused BWA index data as a part of maintainance activities.
And as you mentioned in your case, you have few cubes , it would be best if you automate the process of deleting,creating and filling the BWA indexes of the cubes using a process chain that can be scheduled to run on a weekly/required frequency depending on the data volume.This will save a lot of manual effort.
For steps on the same, please see my response on the below thread:
