IC Multi Level Categorization Import- Subject profile and Subject Codes not picking

Hi Experts,

We have a strange issue. When importing the schema from Development system to Testing system, via RFC, we see that the structure of the Categorization is picked up in the Testing system, but the schema does not pick up the Subject profile and subject code. We have 4000 entries in the scheme and it will be practically impossible to select the subject code for each of these again.

Please help and points will be awarded for helpful  answers.

Thanks,

Karthik
