Automatic OP clearing when using an alternative payer

[S0023814872]

Hello community,

I have the following challenge.
We only use FI in the public cloud. We receive the invoices via interface from a pre-system. The open items and payments are then managed in the public cloud.
We are increasingly working with payment advice notes and automatic clearing of open items. In this scenario, we have the problem that we have different payers. In other words, the customer is the invoice recipient, but the payment advice note and payment come via a different payer. (e.g. central settlement) The open item is for the customer, we have filled the “Alternative payer” field in the business partner with the corresponding payer. We had hoped that when processing the payment advice note, the system would automatically recognize that the alternative payer wants to settle the customer's corresponding open item.
Unfortunately, this does not work.

We have only defined the business partners with the role FLCU00 (customer) and do not use any sales data, and therefore no partner roles in the system.

Does anyone have experience with the “alternative payer” function or with the scenario I have described?
I would be grateful for any ideas.

Thanks in advance for any guidance!

Alex

In SAP Public Cloud (FI-only), the Alternative Payer field in the Business Partner does not automatically trigger clearing when using payment advice.
To enable automatic clearing:
1. Define a Clearing Rule in Transaction OB74 to allow open item clearing between the customer and alternative payer.
2. Use a Customer Clearing Account (via F-30 or F-32) to link payments to the correct open items.
3. Enable BAdI Implementation (e.g., FI_PAYMEDIUM_SAMPLE_41) to enhance payment processing logic.
4. Ensure Alternative Payer is Assigned in the Payment Advice and Document Posting.
5. Check Automatic Clearing Configurations in SAP S/4HANA Cloud SSCUI settings.
