ABC_TPLINF 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 "Information for Work Areas/Tables in Process Template" 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_ABC_TPLINF TYPE ABC_TPLINF.
The ABC_TPLINF table consists of various fields, each holding specific information or linking keys about Information for Work Areas/Tables in Process Template data available in SAP. These include ENTRY (Table Name), POS (Current Number in List)... 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. .
