LSMW Recording for Transaction Data – FB01

In SAP ECC, LSMW tool is preferred for Master data uploads. For transaction data, most of the time BDC recordings are preferred over LSMW. It’s a belief that FB01 recording in LSMW is not feasible. This is untrue. LSMW can be used for FB01 recording.

In this blog focus will not be on LSMW recording steps. Prime focus will be on significant steps required for FB01 recording.

Pre-requisite: Readers should possess basic LSMW knowledge.

This blog coves below steps.

      Hi Zunaid ,

      your FB01 LSMW recording is nice and fine but bear in mind that it records the screen numbers. Each posting key triggers a different screen. So for example if you make recording for vendors you cannot reuse it for vendors with special GL indicator because it calls different screen.

      Therefore it is better to use the batch input program RFBIBL00 that by its own chooses the correct screen or BAPI_ACC_DOCUMENT_POST (yes, you can use BAPI in LSMW).

      Hi Marek,

      Thank you for your message. I hope you are safe and doing well in this COVID pandemic.

      I agree with you. Purpose of this blog is make community aware of this LSMW feasibility. This can also be adopted for other tcodes like FB50. This blog could be very helpful for last moment uploads or one time upload.

      For fix and regular upload, we often write BDC or use standard LSMW programmes.

      Please keep sharing your inputs and i highly appreciate your above message.

      100% agree.  I don't know why people continue to use BDC-based solutions when a BAPI is available.  Speed, ease of use, error correction, error management... all of it is easier with a BAPI.

      You can wrap LSMW project with SE38: /SAPDMC/SAP_LSMW_INTERFACE and a variant into a transaction allowing for users only execution steps.
