GRRM_S_DIMTYPE 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 "Structure - Dim Type" 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_GRRM_S_DIMTYPE TYPE GRRM_S_DIMTYPE.
The GRRM_S_DIMTYPE table consists of various fields, each holding specific information or linking keys about Structure - Dim Type data available in SAP. These include RFC_DEST (Logical Destination (Specified in Function Call)), PARAMETERIZATION (Character 100)... 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. .
