RFVD_ACTIVITY_TYPE 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 "Activity Type (Control and Text)" 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_RFVD_ACTIVITY_TYPE TYPE RFVD_ACTIVITY_TYPE.
The RFVD_ACTIVITY_TYPE table consists of various fields, each holding specific information or linking keys about Activity Type (Control and Text) data available in SAP. These include XDESCR_SHORT (Short Name), OBLIGATORY (Checkbox), OPTIONAL (Checkbox), HIDE (Checkbox)... 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. .
