SAP EWCTRANS Screen Fields: Data Flow Maintenance Table data and field list

EWCTRANS 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 "Screen Fields: Data Flow Maintenance" 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_EWCTRANS TYPE EWCTRANS.

The EWCTRANS table consists of various fields, each holding specific information or linking keys about Screen Fields: Data Flow Maintenance data available in SAP. These include DELEMENT (Target element), PRIORITY (Priority for a data flow definition), DCOMPONENT (Component of target element), ELEMTYPE (Element type)...
