Mass Allocation across ledgers

Hi, We are trying to create a Mass Allocation formula across ledgers. In the formula, we are using Ledger X in line A, and Ledger Y in the Target and Offset Account. When we are trying to generate mass allocation journal, the program is ending in warning with Error D. But, we have ensured that there are balances in the cost pool account, responsibility used has read write access to both the ledgers, Balancing segments are assigned to both the ledgers. Could someone please advise if we are still missing something?Mass
