RSDMSM_MAP 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 "Map of source fields to model fields" 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_RSDMSM_MAP TYPE RSDMSM_MAP.
The RSDMSM_MAP table consists of various fields, each holding specific information or linking keys about Map of source fields to model fields data available in SAP. These include COLUMNNAME (Model Field Name), COL_DESCRIPTION (Description), SRC_FLD_NAME (Source Field Name), DSRC_FLD_NAME (Display name for elements in Source)... 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. .
