I have created a user TridReadWrit (not admin user) in tridion and assigned to group Developer
The user has Read/Write permission on Tridion Building Blocks.
Below permissions are enabled for the user- Permission is set at ‘Test Publication’>Property>Security Tab> Developer Group
- Publication Management
- Folder Management Structure Group Management
- Schema Management
- Component Management
- Component Template Management
- Page Management Page
- Template Management Publish To Content
- Distributor Workflow Management
- Category Management
- Template Building Block Management
- Virtual Folder Management
Also I tried set all permissions except -tried second time ‘Test Publication’>Property>Security Tab> Developer Group
- Publication Management
- Permission Management
Both the situations the user TridReadWrit not able to delete Page Template(created by the same user)
You have to provide delete permission to user or group. Go to building blocks folder containing PT and and choose Properties in the context menu.
In the security tab assign the Delete permission to user or group.
Hope it helps.
