SAP EWM modules :

Here we come to the actual topic of the post, the SAP EWM supports a lot of different functional modules. Let’s start learning them one by one;

In this blog, we are going to concentrate only on the functional modules and customer existing transactions. Each functional module is combined with the transactions to create a simple screen or to enhance the current available functional module to meet the specific customer’s requirements.

Processing TRs(transfer requirements) using the functional module :

This type of functional module allows users to create or change the transfer requirements in the warehouse management. You can make use of these types of functional modules instead of using batch input processes this improves the performance of batch input processing.

To perform this action, the following are the important functional modules available:

L _TR_CREATE_CHECK ->this functional module helps to perform plausibility checks.
L_TR_CREATE_UPDATE -> this functional module helps to database updated according to plausibility checks.
L_TR_CREATE -> perform plausibility checks and database updates.
L_TR_CANCEL -> cancel plausibility checks and database updates.

Processing TOs using the functional module :

In warehouse management, users can create, confirm, and change the transfer order using the various functional modules. Let us make a list of them;

Report SAPML03T -> this Report SAPML03T consists of the screens and tasks necessary to process external documents.
Function group LO34 -> this function group contains the essential internal data for creating and confirming the transfer orders and calls up the update program. The function modules from group L034 are for internal use and are therefore not released to customers.
Function group L03B -> this function group L03B contains the functional modules that you should use instead of batch input or CALL transaction using since they are considerably easier to manage.
L_TO_CREATE_SINGLE -> create a transfer order (TO) within a single item.
