Sourcing Assignment: Different Categorie Sets for Purchasing and ASCP?

Dear all,

We are on R12.2.5 with EBS and ASCP on two different instances.

What we would like to do is to

• maintain the assignment set for purchasing items in EBS (Purchasing Super User) using the purchasing category set and
• maintain the assignment set for internal sourcing in ASCP using another category set.

So the question is: may I assign different category sets to the respective profile options:

• MRP: Sourcing Rule Category Set  = purchasing category set
• MSC: Sourcing Rule Category Set  = another category set.

The system allows me to do it but I am wondering whether this really is supported.
