What’s happening?
Customers are unable to post a voucher containing multiple vendors in different lines, despite having the parameter ‘Apply multiple transactions in one voucher’ activated. The error message received states, “There can only be one vendor transaction per voucher.”
Reason:
This arises when there is a value in the invoice number field. The system has a validation that restricts multiple vendor transactions on a single voucher, which is a long-standing limitation that exists independently of the ‘One voucher’ parameter.
Resolution:
- Ensure that the invoice number field is left blank when attempting to post a multi-line vendor voucher. If the invoice number is populated, the system will trigger the error.
- If the error persists despite the invoice number being blank, it may be due to custom code affecting the functionality. Further investigation into the customizations may be required.
