Upload Master Data Using the BAPI Method in SAP LSMW

When batch input recording is too cumbersome for uploading data, you can use a BAPI using SAP Legacy System Migration Workbench in SAP ERP Central Component. See how to do this with specific reference to Flexible Real Estate Management.
Key Concept
You can do data conversion through batch input recording, direct input, BAPI, or Intermediate Documents in SAP Legacy System Migration Workbench. Some modules require you to use certain methods, and one such circumstance is that Flexible Real Estate Management requires you to use BAPIs.

Legacy data transfer is one of the most critical events during an implementation. Normally, you use batch input recording for uploading data. However, depending on the complexity of the application, you need to use a different method of data transfer in SAP Legacy System Migration Workbench (SAP LSMW).

For example, you cannot use the batch input recording method if the input screens are not standardized. In such cases, depending on your initial input, subsequent input screens might change, leading to overly complicated recording and setup.

Also you cannot use the batch input recording method if there is no 1-1 relationship between the field and input (i.e., you can provide more than one input into a single field). You often have a scenario in which one real estate contract has 10 objects attached to it, while another has 20.

It might not be possible to handle these scenarios through batch input recording. Even if you can do it through an out-of-the-box method, the recording becomes so complex that it is not worth the effort. These complications occur as the SAP system inputs these values through the front-end program using the batch input recording method.

I'll explain the legacy data conversion of real estate contracts using BAPIs in SAP LSMW in Flexible Real Estate Management (RE-FX). Even though RE-FX is my example, you can apply the functionality to other components depending on the availability of SAP-delivered BAPIs (e.g., FI-AR, FI-AP, FI-AA). While converting data through BAPIs, you input the data directly through the target data structure, whereas in the case of the batch input recording, the data is input through the front-end program.
