Edit button on related list not displaying

[mballinger]

Hello,

I have create a M2M table between 2 Scoped Apps. The M2M table creation automatically creates 2 related lists. As an Admin, I have no issue using the "Edit" button. When I impersonate a user, they are unable to see the "Edit" button. I was trying to go down the ACL path, but write access is given to the "snc_internal" role on both tables. I'm not sure what to look at next. 

Is the issue because the M2M relationship has been created using 2 scoped apps?

What can I do to fix this?

Thanks!

***EDIT***

I checked the List Control and there are no rules on the Edit button and "Omit edit button" is not checked, so the List Control is not the issue

Hey,

It will be difficult to answer without access to instance. There are SN to resolve this issue, checkout Resolution in the below link:

Cause

• List Control settings are restricting visibility to the Edit button
• Users do not have create or write access to either the child table or the field in the child table that references the parent table
• The field on the child table that references the parent table is not configured as Reference Floats
• The first record in the related list does not have create or write access to the child table or the field in the child table that references the parent table
• The UI Action is restricting visibility to the button

The issue was I needed to add security rules on the M2M table. Thanks!
