RMF64C 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 "Internal table for position management" 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_RMF64C TYPE RMF64C.
The RMF64C table consists of various fields, each holding specific information or linking keys about Internal table for position management data available in SAP. These include BUKRS (Company Code), SANLFBEZ (Product Category), SANLFREF (Product Category), RANLREF (Reference security ID number)... 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. .
