Hi Imran,
In my current assignment, we got no need to implement this . I am giving you inputs from past experience .
but i have a question for you, have you ran a query on cube to compare the stock value and stock qty against MB51/Mc.1? If you have done the intial data loading correctly during the non-business hours and compare the data, it should match. please confirm have you done these correctly?
in which environment are you working ? Dev/Qa/Prd ? if you are working in dev and not sure about mappings then you can always compare it with QA/PRD if your business already gone live. alternatively, you can post your current mapping here to get more help. Thank you
