SAP EMS_UDF User-Defined Fields Table data and field list

EMS_UDF is a standard SAP Structure so does not store data like a database table does. It can be used to define the fields of other actual tables or to process "User-Defined Fields" Information within sap ABAP programs.

This is done by declaring abap internal tables, work areas or database tables based on this Structure. These can then be used to store and process the required data appropriately.

i.e. DATA: wa_EMS_UDF TYPE EMS_UDF.

The EMS_UDF table consists of various fields, each holding specific information or linking keys about User-Defined Fields data available in SAP. These include FAC_ID (Asset ID), DOM_TYPE_KEY (Key for Domain Type), DATA_TYPE (Actual/Target Data), KV_TECHNICAL_ID (Key-Value: Technical ID)... See below for full list along with technical details, documentation, text table, check tables, foreign key relationships, conversion routines, relevant tcodes and example ABAP select code etc. .
