HAP_S_ADMIN_FUNCTION 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 "Administrator Function" 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_HAP_S_ADMIN_FUNCTION TYPE HAP_S_ADMIN_FUNCTION.
The HAP_S_ADMIN_FUNCTION table consists of various fields, each holding specific information or linking keys about Administrator Function data available in SAP. These include CATEGORY_ID (Appraisal Category ID), PLAN_VERSION (Plan Version), TEMPLATE_ID (Appraisal Template), SORT (Sort)... 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. .
