RODPS_REPL_S_FIELDS 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 "Source Object Field" 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_RODPS_REPL_S_FIELDS TYPE RODPS_REPL_S_FIELDS.
The RODPS_REPL_S_FIELDS table consists of various fields, each holding specific information or linking keys about Source Object Field data available in SAP. These include TYPE (Data Type in ABAP Dictionary), LENGTH (Length (No. of Characters)), DECIMALS (Number of Decimal Places), OUTPUTLENG (Output Length)... 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. .
