comparing fields data between two tables from two different systems
Can anyone please tell me "how to compare the SOME fields data between SAP ECC - MARA and SAP MDG-MARA tables" in either SAP Data Service (or) SAP Information Steward tools .
For example , to compare the data for field MARA-BRGEW in both ECC MARA table and MDG MARA table . Here idea is to get know how many records are different between two system tables . Actually data is moving from ECC to MDG on daily basis so business wants to know how many fields per a particular table(MARA or EQUI) are correct between two systems(ECC and MDG)
Please let me know the high level solution .
