Hi everyone! After creating a new tab for a sales order form and adding screen fields, I can’t see the fields when editing the Custom Transaction Form. I also can’t add any field groups to that tab. Any ideas why?

When creating the fields, did you apply them to that particular form? You can do so by editing the custom fields and clicking on the button labeled: "apply to forms"

Thanks @Dennis Kuiper I applied one of the fields to the form and all of them showed up
