Hi Raj,
My understanding was this:
You enhanced BW cube with 2 fields, move to prod. everything was fine.
On BPC Side you loaded data from BW Enhanced cube by usig DM pkges as-usual. But your BPC cube was doubled after this load.
If yes then, Check as suggested above.
One more major point here. You did bw cube enhanced as your business in BW only(guess). For added fields you may be loaded historical data. am i right.think so.
So now your BW cube have historical data till now. When coming BPC cube, you may not be deleted data from BPC Cube (old data) which you loaded,because its not necessary. If your BPC have some data before this load, then after this load its may doubled. because BW Cube have historical data. BPC Cube old data was lied in bw historical data, whatever option you used at DM pkg, you get double.
Even if you loaded delta pkg at BPC side also you will get doubled. because source bw cube have old data in new request form.
for BW enhancement - BW deleted data and reloaded
For BPC - didn't deleted,without deletion, data requested from bw cube, so bpc data will be double.
Work around: if above my points are right then you just delete BPC cube data and reload whole again.
When enhancing BW cubes which are used in BPC models. need to remember about this data issue.
Thanks.
