| Error message from M3 | NOK Year must be entered WYEA102 |
| M3 programs | APS200, APS450 |
| Type of message | Reversal - invoice not found |
| Has the invoice already been (partly) posted in M3? | Yes - the invoice exists in M3, but the reversal has not been carried out. Check this in M3. |
What does this message mean?
When reversing the invoice, the invoice cannot be found by the invoice number as held on the invoice header. Because the invoice is not found, the year for the reversal cannot be determined.
What to check
- Check under which invoice number the invoice is held in M3.
- Check the audit in AP Automation for an earlier ERP error. The invoice number is often changed afterwards, which means it no longer matches.
How to process the invoice further
Ask ISPnext through a case to move the invoice one step forward in AP Automation, or move it forward yourself from the ERP error activity with the option Corrected in ERP.
More information
Another message that occurs when reversing is M3 error message: Option 4 is not permitted for an invoice entered as approved for payment.
Once you have corrected the invoice in M3, you move it forward in AP Automation with the option Corrected in ERP. See Moving an invoice forward with "Corrected in ERP".
The article M3 error messages - introduction shows how the M3 error messages are organised and describes the approach that applies to all of them. If you are looking for a specific message, search for the text of the error.
