Import of new Vendor credit: Error of "You cannot edit the account of the transaction line that is linked to others."

On the mapping, set the Auto apply box to False.

• There are bill transactions on the apply tab that is from different subsidiary.
• This error is a mismatch on the subsidiary of the bill credit to bill transaction.
  

Best way to test this is to create the bill credit manually:

1. Navigate to Transactions > Purchases/Vendors> Enter Vendor Credits
2. Set the Vendor Name
3. On the Account field, enter the Accounts Payable account on the CSV file
4. Navigate to the Apply tab

There are bills from different subsidiary for that vendor.
