Error during Model mapping when importing AP invoices from SharePoint — Italy only

(1) ShareShare
ReportReport
Posted on by MP-18022054-0 4

Hi everyone,

 

We are facing an issue when importing AP invoices from SharePoint in D365 F&O. The problem seems to occur only for Italy.

 

During the import, the process fails with the following error:

 
 

This happens during the Model mapping step.

 

What we have checked so far:

 


  • We reviewed the ER model mapping and could not find any field or expression where a GUID is explicitly used.


  • We also checked the report related to this process and could not find any obvious GUID reference there either.


  • The issue appears to be Italy-specific only.


  • Other legal entities are able to import AP invoices from SharePoint without this error.


  • The error suggests that somewhere in the Italy-specific setup, mapping, metadata, or localization logic, a value expected to be a GUID may be blank or incorrectly formatted.


    •  
 

Has anyone seen this kind of error before during AP invoice import from SharePoint or during an ER Model mapping run?

 

Any suggestions on where else to check would be appreciated, especially around:

 


  • Italy-specific ER configuration or model mapping


  • SharePoint metadata used by the import process


  • AP invoice import setup



    •  
 

Thanks in advance for any advice.

    Can you please add the screenshot of the error message again? Something went wrong because it's not visible. Or, you could just add the error message as text to your post.

    An error occurred during the ‘Model mapping’ run.

    For more information, contact your system administrator.

    Guid should contain 32 digits with 4 dashes

    Do you have GUIDs in the source file or are you missing GUIDs in the source file?
