Introduction:

It is common requirement in the most of SAP implementations to meet the business requirements to enhance the standard screen with the custom fields. There are many different ways to enhance the tables and the dependent screens as well.

When it comes to EWM, most of the projects are/were using the transaction code ‘EEWB’ for the custom table field/screen enhancements to meet the business requirements.

This functionality is only valid for the custom field enhancement used in EWM warehouse/storage type view.

SAP introduced the app called ‘Custom Fields and Logic’ to reduce the cost of implementations. This is a simple but powerful tool. SAP is adding many new business contexts in each release.

SAP added central S/4HANA extensibility framework in SAP S4 2020 FSP01 for EWM product master. This framework allows to add the custom fields for storage type data view and warehouse data view of the warehouse products.
