Hi @Ed22 , if you create a custom field on an entity you will still have to manually add it to the page(s) where it needs to be presented.

You can do this by navigating to the page, go to your account at the top right and press page designer. This will open the page designer where you can add the custom field. 

For more information on how to use the page designer see Introduction - Aurena Page Designer - Technical Documentation For IFS Cloud

If it still doesn’t work, please clarify whether you want to add custom fields or custom buttons (ideally with screenshots).

Then Page Designer is the right tool:
 

Scrap, rellocatoon, availabilty...if they are buttons why cant I see them?

Firstly, this is a preview of 24R2. :-)

Secondly, have a look at the details of the command. Very often they are conditionally enabled. It may be your permission, it might be something on the record e.g., the current status. 

But I still dont know why cant see them, should I update something in enabled or grants? Can I add button whethever I want, for example near search button?

The buttons are context-sensitive, so you need to select one or multiple rows for the buttons to show up. You can only add buttons here…

...not near the Search button (this would be out of context).
