SAP WRF_NEEDED_TYPES Characteristic Types Table data and field list

WRF_NEEDED_TYPES 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 "Characteristic Types" 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_WRF_NEEDED_TYPES TYPE WRF_NEEDED_TYPES.

The WRF_NEEDED_TYPES table consists of various fields, each holding specific information or linking keys about Characteristic Types data available in SAP. These include L_CHAR_TYPE_1 (General Flag), L_CHAR_TYPE_2 (General Flag), L_NAME_TYPE_0 (PRICAT: Characteristic attribute), L_NAME_TYPE_1 (PRICAT: Characteristic attribute)...
