What I now found out is that in the one application where it is working, (Application A), I can choose from different Archive Runs. However, I don't have to select one to get OLI1BW running, I can leave it blank.... where in application B I cannot run OLI1BW because as explained it cant run without filling in a valid value for field Archive Run. It doesnt give an error, the cursor keeps on staying in the Archive Run field when I try to execute.
So perhaps the next step is to create an Archive Run in application B..
