Lockbox (FLBP) processing and posting of application document from FINSTA01 idoc

[Former Member]

Hi All,

   I require some clarifications regarding the lockbox processing of incoming customer payments,  Please correct me if my understanding is wrong about the standard process ( although we have a slightly different process for out customer), I am only concerned about the EDI processing

• Customer send payment to bank via the specific lockbox
• Banks process the payments and send a file to the customer which is interpreted by the EDI subsystem  to create 823 file with type FINSTA01 this is bank payment details
• Customer send the remittance details via a flat file which is then converted into an 820 files (question here how both files  EDI 823  & 820 would be matched while processing is the during the main lockbox processing ?
• The program RDBAPP01 (BD20) using the FM IDOC_INPUT_LOCKBX is called to post bank statements, payment advices using EXIT_SAPLIEDP_201 to EXIT_SAPLIEDP_203
• The above program update the tables FEBEP, FEBKO, AVIK and AVIP
• The main lockbox program RFEBLB30 used for EDI file processing posts the to the G/L accounts as well as the subledger accounts for fully applied as well as for partially applied and un-applied payments
• Post processing is done via FLB1 for partially applied and not applied payments

My biggest doubt here is how does the system recognize and match the EDI 820 & 823 files in standard SAP functionality, however we have Z program to merge and apply payments I am more concerned about the Standard SAP functionality,

Please Clarify my concerns 

Points promised

Hi,

820 remittance is electronic payment by an org to its vendor. So its direct bank to bank transfer. There is no check involved.

823 file received is check payment from customers through a bank. Customer sends a physical check to bank. Bank will collect the info in the check and send an 823 file to the organization.

From your statement above I believe you are thinking that 820 remittance from an org to a vendor should have the same info as 823 file received by the customer.

You cannot compare the 2 and SAP does not reconcile 820 and 823. There is no process in SAP. Hence you need to revisit your assumption on the observation you have made.
