In Lawson you may be creating a custom ESS form that you don’t want users to be able to get to (assuming you removed the search button).
Example of this below:
Open design studio by going to https://yourcompany.domain/lawson/studio
To remove these related forms, edit the custom form in design studio and remove transfers id in source:
Save the now custom form, make sure it is set to default in logan or is accessible via a bookmark direct URL.
Clear your IOS Cache and test to make sure the related button is now gone.
