SAP BW 7.3 - Error DTP RSBK241

Hi,

We're running the DTP to a Z infoCube from a PSA.

The DTP ends with the following error message (number RSBK241):

"Error while updating to target ZXXX (type INFOCUBE). Message no. RSBK241"

We had reactivated the infoCube, the transformations and the DTP, and we still get this error.

We also took into consideration the following SAP notes, but they didn't solved the problem.

The log job of the DTP is:

/BIC/FDWCJCSTMA0000000034" REBUILD UNUSABLE

We think it might be a data error. Is there any way of debugging it to find the data error?

Any ideas how to fix this?

Thanks in advance,

Florencia
