Addition of dims to exising model created new backend cube

Hi Friends,

I have added 11 new dims to existing model  X, which already consists of 9 dimensions. 

Before addition of new dims, model  had two back end cubes X  and X_B.

After addition of dims, today new cube with 20 dims created. Old cube still exists I mean system not deleted. UJA_APPL points to new cube.

Short dump says program struck at

Call program........."SAPLUJN_API_BI_IOBJ"

  Function module "UJN_API_DELETE_CUBE"

  Call destination.. "BPCRFC"

Data loading and report retrieval is happening via new cube.   

How to handle old cube ? I mean can we ignore that or need to apply any note or SP.

Ours is BPC 10 NW.
