LSMW - import technique decision task

[Former Member]

We are live with financial accounting in SAP 4.6c. We currently have a project underway to implement Accounts Receivable. Most of the receivables originate from mainframe billing applications. As a result we will be processing receivables via interface regularly. According to the LSMW documentation this tool can also be used for periodic interfaces, so we would like to use it. However we don't know what the considerations are in order to decide whether to use batch input (RFBIBL00), BAPI (BUS6030) or IDOC (ACC_DOCUMENT) to process the incoming receivables. Does anyone have any relevant experience to share?

RFBIBL00 is the SAP delivered direct-input program!

It has always worked for me! You can even write your own pre-processing program and submit your data to RFBIBL00!

Read its documentation from SE38!

Yes, we know about RFBIBL00 and it seems like the path of least resistance, but we are also currently in the process of rewriting our invoice verification input program (Batch) to comply with the requirements of LIV (IDOC). For that reason we're sensitive to selecting an import technique for this data that won't need to be touched when we upgrade to mySAP ERP or expand our business processes to the web.

Thanks,
