3657821 - How to Restrict Modelers to Only Adding (Dimension) Values to a Model for SAP Signavio Process Manager

Variant Management (a brief introduction)

Ref: Variant Management | SAP Help Portal 

In SAP Signavio Process Manager, process variants represent ... different perspectives on a main process. 
For each variant, you define characteristics that differentiate it from its process template and from other variants.
These characteristics are implemented as dimensions (dictionary categories) and values (dictionary entries).

Feature Sets

For users who will be managing Variants, there are 2 main Feature Sets that need to be enabled, in the group they are a member of.

NOTE: In this context, manage means create & select.

Dictionary Access Rights

Modelers have V, W, D access to Dictionary Categories that have Use for Variant Management enabled.

• V = View
• W = Write
• D = Delete

The Problem

How to restrict Modelers so that they can add Values to a Model, but not add Values to a Dimension?

With the above Feature Sets enable, and the Dictionary Access Rights granted, Modelers can add Values to a Model, and add Values to a Dimension.
(Reminder: dimensions (dictionary categories) and values (dictionary entries))

For Dictionary Categories that have Use for Variant Management enabled, grant Modelers V (View) access only.

This means they cannot add values (dictionary entries) to a dimension (dictionary category), but still add (Dimension) Values to a model.
