I notice some inconsistency in FF7B Liquidity forecast report. For Customers (Payer), we have defined the invoicing dates as End of Month by assigning an appropriate factory calendar. (KNVV-PERFK) Also lets us say we have assigned a payment term that states 7 days due net from Document date.
Now when the Actual Billing is generated for all the deliveries effected through the month, say from 01 Nov to 30 Nov, the Billing date for all these deliveries becomes 30th Nov and the Net Due date (in FBL5N) is shown correctly as 07th Dec.
So, it looks all seems to work fine on the FI side.
Now when we run FF7B and drill down to check forecast details for Sales orders, (Level S1: Sales Orders), the report shows the planning date as Delivery date + 7 days. This is incorrect as the planning date should be end of month + 7 days for all deliveries.
I could not locate any OSS note for this issue applicable to EHP7 for SAP ERP 6.0. Any idea how this can be corrected on the Cash Management and Liquidity Forecast side.
