Hi Rebecca,
The behavior you're describing—where an error message appears intermittently when opening certain forms in your customised D365 Finance and Operations environment—is not uncommon, especially in environments with customizations.
Here are a few considerations:
Since the issue is not consistent and seems to resolve itself upon reopening the form, it's likely related to:
If possible, check the browser console (F12 > Console tab) or the server logs for more detailed error messages when the issue occurs. This can help pinpoint whether it's a client-side script issue or a server-side problem.
There are no widely reported platform bugs in standard D365 F&O that match this exact behavior. However, Microsoft does release hotfixes regularly, so it’s worth checking if your environment is up to date.
Sometimes, clearing usage data for the affected user can help:
If possible, test the same form in a non-customized environment or with customizations temporarily disabled. If the issue disappears, it confirms the root cause lies in the custom code.
If the issue persists or becomes more frequent, it may be worth raising a support ticket with Microsoft or reviewing the customizations with your development team.
Please verify if this response was helpful.
Best regards,
Daniele
