I am trying to Execute ABAP data flow getting the above error, when i spoke to basis team they said The client A is not open for Repository changes. You have to make changes in client B and then SCC1 to A.
I think you will need to set dataservices to execute only (rather than generate an execute). The code will need transported from B to A by your Basic guys.
This assumes you are able to run your job against B first though…
