FMRSD 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 "FM Rebuild of SD Orders" 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_FMRSD TYPE FMRSD.
The FMRSD table consists of various fields, each holding specific information or linking keys about FM Rebuild of SD Orders data available in SAP. These include VBELN (Sales and Distribution Document Number), ERDAT (Date on Which Record Was Created), FMSTK (Status Funds Management), TEXT (FM: subsequent Posting of SD order)... 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. .
