Changing circumstancing from single variable to multiple variables
I created a rule long ago that uses single variable circumstancing; now I need to change it to use multiple variable circumstancing. I have tried the following to update the circumstancing:
1) Create a copy of the single variable rule (a section in ruleset version 78) that contains the same circumstance into a higher RSV - 87 and withdraw the section. Then create a copy of the section using multiple variables in RSV 88. I received an error (below).
2) Create a new base version of the rule in a higher RSV - 87 then create a section using multiple variable circumstancing in RSV 88.
No matter what I try I get this error: pyCircumstanceProp—
This rule already has a circumstance property defined (.PropertyName); you cannot give it another.
When I look at the XML on the base version of the rule in RSV 87 the pyCircumstanceProp is empty.
How do I update a single variable circumstanced rule to use multiple variable circumstancing?
