Different Reference data set for credit memo(AR) - Transaction type

Summary:

Hi

Can we use different reference data set for Credit memo in AR ?

Currently we are using reference data set on the basis of our unit . For Ex - Unit-A having a separate reference data set

Unit Name - A

Reference Data set used - A(reference data set)

Business unit set assignment

Transaction Type - A( Reference data set)

Now we want to want to use Different reference data set for Credit memos for example - Credit Memo Reference data set by keeping the same RDS on transaction type i.e A(RDS) on business unit set assignment .
