Masking can be used to track cash in multiple General Ledger cash accounts. For example, to track cash in multiple funds after creating the General Ledger account numbers, use masking in the Fund dimension, like XX-1000-00. If you do this for your Accounts Payable module and enter an obligation in Fund 01, the cash account credit would be 01-1000-00. If you entered an obligation in Fund 02, the cash account would be 02-1000-00.
