How to Identify Unused Code or Elements

Posted on by D365Explorer

Hello,

I’m looking for a way to identify unused code or elements in D365FO, such as tables, enums, classes, etc.
Additionally, is it possible to find these unused elements on a model basis? If so, what tools, techniques, or best practices would you recommend?
Any guidance or tips would be greatly appreciated. Thanks in advance!

Regards,

Hi @D365Explorer,

To know if the element is used or not you can right click on the element, click find all references, if it doesn't have any reference, so you know it is not used.

Thanks,

Hi D365FO Explorer,

As far as I'm aware there is no straight forward way to get the result of everything not being used.

As waed said, you will need to go to each AOT element, and right click "find references"

Hello Waed, Layan, and Ramesh,

Thanks a lot for your replies, really appreciate the help.

I’m aware of the "Find References" option by right-clicking an element, but as you know, that works one element at a time. The challenge I’m facing is that I don't know exactly which elements might be unused, and checking them one-by-one would take a lot of time across a big custom model.

I’m hoping to find a way to scan an entire model and get a list (even if it's not 100% perfect) that shows potentially unused AOT elements or logic. Even an approximate result would be super helpful and save a lot of effort.
If you know of any tools, scripts, or any other ways to do a broader search across a model, please let me know.

Thanks again for your time and support!

Best regards,

Hi D365Explorer,

There is no option to scan for unused elements. If the cross-references are updated for the custom model, the data is stored in a SQL database. You can try to query that database and get a count of references per object. This is still cumbersome as there might be an unused table having an unused form and also unused classes with some X++ coding referring to the unused table.

Hi Andre,

Thankyou for the clarification.

I have a related question:

I’m currently working on a code upgrade project. During the upgrade, some elements are no longer being used because parts of the logic have been re-written to align with D365FO standards, and some references have been modified to meet specific requirements.

In this situation, what would be the recommended approach to refactor and safely remove the old unused references and elements?
Is there any general approach you would suggest for identifying and cleaning up unused code during an code upgrade?

Regards,
