Error when Create Accounting for INV transactions

Dear All,

We are create accounting for INV Transaction. But system show error "The segment value THC_Company in account 120.0000.0000.153999.0000.00000.000.0000.0000 isn't assigned to ledger THC_Ledger VN. Details: You must either modify the account rule to use a different balancing segment value for the journal line or assign the balancing segment value to the ledger."

After that, we assign the balancing segment value THC_Company "120" to the ledger THC_Ledger VN.

We created accounting for INV Transaction again.

System show "You must either modify the account rule to balance the journal by balancing segments or enable intercompany balancing for ledger THC_Ledger VN."
