Cannot load 0COSTCENTER hierarchy

Hello experts,

(This error is happening in our QA environment, but DEV environment works OK. Both systems are on the same components level)

We're facing an issue trying to load one of our hierarchies into BPC from BW. We're loading 0COSTCENTER data, we've 2 CO_AREA, with 2 hierarchies (one for each CO_AREA) as is shown here:

For the 2nd hierarchy (CO_AREA GEBI), we can load master data and hierarchy nodes correctly, but when we try to load master data + hierarchy nodes for the first CO_AREA (EEB), the system shows the following BPC warning:

In the /CPMB/IMPORT_IOBJ_MASTER package, we're passing correctly the parameters as is shown:

Transformation and Conversion files are OK, since second CO_AREA works and even if I pass an empty transformation, the same error shows immediately (less than a second every time we try).

We've also tried to pass the top hierarchy node to Member ID parameter, 99 in the Level parameter, everything, but same result.

Our system components in both environments are:

Any suggestions? Any help is highly appreciated.

Thanks in advance!
