If you have a Report link field on the damage parts table and choose to show the root cause records directly on the form, then you also get a choice as to whether that embedded table is editable. That is a setting on the form property for that report link field.
If you make that editable, that means that when you edit the damage parts record the root causes become editable as well in what is called the grid edit format.
However if you have form rules they will not be applicable in grade edit format, and also of course there is a realistic limit to how wide you would want to make that embedded report in terms of the number of fields.
If you have a complicated root cause for him with many fields then it will be more practical to have the users click the pencil icon on the embedded report on the damage parts record and edit on the full form.
Just to confirm, can you confirm that you do in fact have an a better table of the root causes with the records directly showing on the damage parts record?
