Hi..
If you change the account by my BSX account, the situation that the stock amount of MM and FI don’t match will occurs.
Because SAP need the account for gain and loss account as PRD-PRA transaction key.
So, I think that it is impossible to change it.
Generally, initial inventory stocks are upload using the previous month of open date.
In case of materials with moving price, we upload both the quantity and the amount of inventory to avoid price difference.
In case of materials with standard price and material ledger’s activation, we upload only the quantity of inventory and generate the document with difference amount between legacy actual amount and SAP standard stock amount using t-code mr22 and transfer the difference amount into stock amount using material ledger closing(t-code:CKMLCP).
