Hello SS,
Below are some MRP tables, however I personally feel it is much easier to pull MD04 information using BAPI BAPI_MATERIAL_STOCK_REQ_LIST
MDKP, "Header Data for MRP Document
MDTB, "MRP table
MDTC, "Aggregated MRP table items
T457T. "Description of MRP elements
Hope this helps .
Best Regards,
Ameya B.
