This message appears when you try to import a transaction, other than a journal, to one of the following Control accounts:

• Debtors Control Account - by default 1100.
• Creditors Control Account - by default 2100.
• Sales Tax Control Account - by default 2200.
• Purchase Tax Control Account - by default 2201.
• CIS Control Account when the supplier is not a subcontractor.

To resolve this error, simply change the nominal code on the transaction before you import your data.

TIP: To check which nominal codes are set up as the control accounts, in Sage 50 Accounts click Settings then click Control Accounts.
