Without seeing the formula behind [Prior Period Projected on Hand] or some sample data, it is hard to know the exact fix but you can often eliminate a circular dependency by duplicating a measure and using a different name or duplicating its result as a
calculated column and then referencing the new measure/calculated column.
It really depends how your data is set up and how all measures involved are written. Circular dependencies can sometimes be tricky to troubleshoot and the error message often isn't that helpful, but I don't recall coming across one yet in my own work
that couldn't be solved with some clever duplication and/or manipulation of how the formulas are written.
