How to get previous stage name
Suppose there are total 4 stages consider A,B,C and D. I am skipping stages on the basic of Flag (Yes/No
Value). If Flag for that stage ="No" then only case should enter into that stage.
Suppose, Flag for Stages A,B,C and D are "No","Yes","Yes","No" respectively and I am at stage D.
I want the value of previous stage name which has Flag="No" (In this case Stage A) in Stage D. So, I can refer
previous stage name in correspondence .
So how can I get that previous stage name who has value="No"?
