Error when building a grid with member name "Plan"

Content

Hi,

I am using Groovy to build a grid in memory to do some calculations. 

When i use the "Scenario" member "Plan", the grid does not load at all and throws an error. It works fine for every other member in the Scenario dimension.

I am more curious to know whether "Plan" is a member we cannot use in Groovy or is there any property that I have missed looking at or is there any other reason for the grid not to load specifically for this member.

Thank you.
