Lean types were added to .Diagram Defined Custom Properties v18.2 (DDCP) for VSM. They will be used for calculations to the timeline and summary box.
Possible lean types
This is shown when the property type that is selected does not support a leanType. This will default to a value of "none" and be ignored when doing calculations for VSM.
While they can't be deleted from the DDCP they can be set to a value of none. This will make it so that they have no affect to VSM diagrams.
Existing DDCP that are in diagrams that existed prior to VSM release can be updated to set a Lean type. This also applies to diagram that's type is changed to VSM.
Additionally property types that have an allowed type mapping can change freely between any of the leanTypes listed above.
