hi expert,
my apology for sending you a lot of my problem because iam a new with this application.. please help me to know more about this..
thank you.
my issue is why when i am using previous function there is no value in first group
please see image below- on the first details on the first group there is a blank space here that i think it should be true
script:
If ({OINV.NumAtCard}) = previous({OINV.NumAtCard}) then 0 else {OINV.U_20STD}
thank you
