Deduction Settlement - Chargeback

We are running into obstacles with charging back a non-invoice related claim investigation deduction.  The receipt the claims investigation is created on is on a parent/umbrella account and the deduction was placed on the child account.  When we try to settle the claim we get the following error message:

Error Log:

1: SYSPARAM: Post to GL is F

2: Source Table : OZF_CLAIMS_ALL

3: Customer site use identifier is invalid for the specified customer

4: An error occurred when creating Chargeback in AR through AR Chargeback Cover API.

The consultants have explained this is due to when we process the claim it goes through the API and looks for the same customer site ID on the receipt, that is on the claim.  If there is a mismatch the chargeback will not clear the process.  We are in desperate need of a solution that does not impact our productivity.
