Hi Experts,
I am facing a issue, i have created transformation where i have written lookup a values into one of the DSO and populate values in current DSO.
It was working correctly in my Development and other systems, but when i moved a transformation to Production this code is not working for some fields. Not sure why. Lookup DSO has a Events in delivery, and i am loading these Events in a DSO which has a Delivery as a Key. But some of the Events are not populating values where in Other systems in landscape it is... 
I can't see records has populated data in New table so issue is before activation.
I have compared generated program those are exact same except date and time stamps. I tried to debug but gets in looks
Any inputs.
Regards,
Ganesh
