previous function issue

25 Views

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
