I posted this question last week Wednesday, 17-Feb-16 and selected an answer from Mike Beargie. My issue is that I've not been able to incorporate MIke's suggestion for the use of the Case function.
I've attached a copy of the first phase of the test script which first identifies a Found Set of records and then Loop through the records setting Global fields. Phase 1 works!
For Phase 2 I wanted to verify that each field has data before the Global field is set. The function IsEmpty is not a Script step that can be selected, so based on the attached script, how would I use the Case function in the Loop steps?
