Summary :
After implementing a billing due list in SAP, the system initializes simulation mode for billing documents, disabling the 'Save' option and blocking the posting of these documents. Re-accessing the billing due list to post collective billing documents also fails as the 'Save' button remains inactive. This issue, related to VF04 and SDBILLDL transactions, stems from a programming error and is resolved in SAP Release 4.6C.
