Help Creating New Column From Summing Another Column
What I am trying to do seems pretty straighforward, but due to my lack of knowledge/experience, I am having a hard time getting it.
I have card that displays the total contract value of of projects assigned to a particular project manager/employee for a given time period. My goal is to create a new column that displays what percentage of the total current contract amount for the whole company each project manager/employee is currently assgined. The issue lies in the fact that I currently do not have a column/measure summing up all current projects by their contract values. So essentially how can I sum the entirety of a column for a given time period in order to use that value for other equations?
