R03B551 apply pending receipt to an invoice

Hi everyone,

I'm trying to apply two documents using the R03B551 process, but I'm not getting the desired result.

Here's the scenario:

I have an unapplied receipt (RU document type) and an unpaid invoice, both documents from the same customer.

I insert both documents into F03B13Z1 and run the R03B551 process, which takes the records successfully but does not apply them.

The expected result is to have the invoice applied to the pending receipt, and both documents are paid.

However, the process does not consider the 'RU' type document and cancels the invoice amount using a chargeback code.
