Writing Access Diagram
There is one writing access diagram per environment.

If several environments use the same protection configuration, the same user diagram must be used in all these environments.
Rules
Installation of a writing access diagram diagram must respect the following rules so as to minimize user management costs:
• Any object must be modifiable by users that may need to modify it, without administrator intervention.
• The administrator should intervene only in exceptional circumstances.
Use
The writing access diagram is used similarly to a diagram. The persons, person groups and writing accesses are handled just like standard objects:
• Creation and modification of the name, etc., are done in the same way as for standard objects.
• Be careful however when you delete a writing access.

Avoid using the
Cut command for a person or person group, as this can result in errors in the writing access diagram if the person or person group is not deleted from the repository or not linked to a writing access.
