Automatic receipting by Company

Hi, my client has recently taken on a new company on JDE 9.1. The new company shares customers with the existing company, but we need to keep invoicing and receipting separate.

I added Data selection to R03B551, R03B50 and all the algorithms (A, B, D, E and F) to say: where Company (F03B14, CO) = 1, and where <> 1 to keep it separate.

But the result is still receipts for Co 1 allocated to invoices from Co 2.

Is there a way to prevent this? I have two distinct algorithms, one for each company. These are being fetched correctly.

I appreciate any assistance or information you are able to share.
