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
