FUNCTIONAL SPEC FOR GL BALANCES
THere is a functional spec for LSMW for uploading gl balances thru FB01. There are feilds like legacy account, sub account and other fields that the business user wants to flow into SAP. But in FB01 there is only one reference field which i have used for legacy account number. How do we create additional fields in FB01 in order to input other fields like legacy sub accounts and other info that would flow into SAP.
I was told to work with crosswalk tables. WHat are they and how do I use them here. Please provide detailed instructions on how to bring in additional fields from legacy into FB01
