M3 error message: Time-out waiting for response (inner response not available in time)

AP Automation did not receive a response from M3 in time. You determine when the error occurred from the support information on the invoice, have your M3 administrator check the server, and then check whether the invoice was fully processed in M3.

What does this message mean?

AP Automation did not receive a response from M3 in time. Whether the invoice was processed is therefore not established.

What to check

1. Determine exactly when this ERP error occurred. You will find that in the support information on the invoice through * > Show Support information > Interface, in the fields ERP_TR_Time and ERP_TR_Date.
2. Have your M3 administrator verify what was happening on the M3 or MEC server at that moment.
3. Then check the processing of the invoice in M3.

How to process the invoice further

• The invoice has been fully processed. Move it forward with the option Corrected in ERP, or have that done through a ticket with ISPnext.
• The invoice has not been fully processed. Find out why the processing timed out. Work through the troubleshooting steps for the message about the cost lines, see below.

Then correct the invoice manually in M3 and move it forward with Corrected in ERP.

More information

The troubleshooting steps are described in M3 error message: cost lines could not be added, total variance is higher then allowed in APS900.

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.
