Filling characteristics in the end routine
I made ODS (A) with 10 characteristics and i made ODS (B) with 20 characteristics. I made the transformation ODS (A) -> ODS (B). 10 characteristics from ODS (B) are being filled in the end routine of transformation. I loaded the data into ODS (B). Befor the activation of data I saw filled all characteristics (new data). But after activation 10 characteristics (filled in the end routine) was empty (activated data).
As per your first post it mentions that you had only 20 fields in ODS B and 10 fields need to be read from ODS A that need to be populated..
As of now there is no other way to do this. You need to do assign constant value manually.
