DTP activation error. PSA metadata inconsistent.

Hi Gurus

I have been trying to activate a delta DTP from DSO to cube. It is leading to error PSA metadata is inconsistent.

Diagnosis

You want to generate PSA/BIC?B00006115(technical name /BIC/B00061150002) but PSA meta data is inconsistent. One possible reason could be required repartitioning

I have searched SCN but could not find only couple of threads which were not really helpful.

If any body can assist me with it would be great and points will be awarded.

Thanks

Naveen
