Forum post in BI General: Re: Collapsed request in infocube-How to get delta back

Yes you are correct SVR,

We can not delete request once it is compressed. Selective deletion is not usefull in this case.

You can try following -- Be careful -- follow steps -- first try in Dev

If you know last requests generated todays delta in base/source ODS and those requests are available in PSA for reconstruction.... then...

1. Delete initialization from this source ODS to all 3 targets.
2. If requests are available for reconstruction, delete required requests from ODS.
3. Now initialize without data transfer from ODS to 3 targets(2cubes + 1ods).
4. Reconstruct deleted requests in Source ODS(it generated delta)
5. Pust delta to 3 targets.

Hope it helps
