Not able to edit datasource in Sitecore content & experience editor in Sitecore 8.2

Question

I am having a issue. The datasource editing seems to disabled for a particular role "Regional Content Author" but is enabled for another in sitecore content & experience editor.

I have analyzed that both the roles have read & write ability for the items (for which we want the datasource to be edited) in the Access Viewer.

Can someone suggest what may the issue?

Hi I figured out what the issue was.

Adding the predefined role Sitecore/Designer gave the necessary permissions to edit Datasource.

I am currently looking how to assign the permissions without assigning any pre-existing roles
