Property not available in the expression builder for deriving the value for Property of Top Member

Summary:

We currently don’t have custom 1 as property to be selected in the expression builder for deriving the value for the custom 1 top member against the cMAS_OCM_3S_NodeType and I am not clear on what change need to be made to add this in.

It looks like it is only the properties that are bound against the operation chart mapping that we can select (screenshot of the operational chart binding keys below).

Therefore at a guess I would say the custom 1 property needs to be added in here for us to have it as a property to be selected in the expression however I have never updated the below and haven’t had any training on it so we would need a second opinion on this first.
