User can't modify notes without Administer Webform & Submission Access

You might need to write custom access controls with custom code.

One easy workaround, that I use is to add an administrative-only notes (textarea) element to a webform and use the OOTB element access controls or the private property. You might even be able to sync the webform submission notes property with the element value.

You might even be able to sync the webform submission notes property with the element value.

I did some testing, and you would need to write a straightforward update hook to sync the element and submission notes values.

Great thank you for the quick answer!

On the other side of the coin, if in fact we don't want them to have access then the notes column may should be hidden? Currently, the user that doesn't have access can see the notes button/link and when pressed there is no response.

I had the same problem recently, but I found that if the target webform is used as a "wenform node" content, the memo can be used without the "ADMINISTER WEBFORM & SUBMISSIONS" permission.

I am not sure if this is the way it was designed to work, but this is how I handled it.

Awesome, thanks so much Ryo, that works!

I am glad I could be of help :)

You can disable(customize).
