Thank you Chandresh.
I understand.
But to me what it seems a flaw is that the Data Flow -whether changed or not- is transported.
The transport is successful (ok w/o errors), and objects are all Active.
Nevertheless, the GPx program from the Transformation seems is not synched properly.
Therefore when runing the DTP it fails.
Yes, running the RSDG_TRFN_ACTIVATE for the Active version of that Transformation fixes the problem, but, once again, I would expect not to have to run such se38.
Thank you for your inputs,
Alex
