Vendor Invoice Workflow Error

Hi All,

We are doing intercompany PO & SO between 01 & 05, but the get an error on all vendor invoices when we want to approve and post the invoice. Please see example below (look at the workflow stop message)

"The province of the source document or source document line could not be updated. One or more accounting distribution is missing a ledger account or contains a ledger account that is not valid. Use the Accounting distribution form or the Posting profile to update the ledger account"

Please suggest me to solve this issue ?


Thanks in Advance...
