Issues with LTMC

I seem to have an issue doing migration with LTMC. I create a project, upload the file, start the transfer, confirm the values, do a simulation and then the import stage. But When I check my functional transaction to see my uploaded object, I cant find it. I see no error in the LTMC screen. I am not sure of what I am doing wrong. Can anyone help?

I'll add to this thread as this same issue frustrated me. If your program / function module in the backend has a problem. (It short-dumps) the LTMC just gets back that it is "Done". Why? Because your data load is running in the background. So your job finishes. To find the issue, look at transaction ST22 in the backend. If the error is that it can't find the function module, that means that you have to regenerate your migration object in LTMOM. So if you change between clients, your migration object will have to be generated for each client. Again I would think there would be an easier answer, but I have yet to find one. So I load my data on 100, then I try to load it on 110. On client 110 it no longer works, generate the object. If you move back to 100 then generate the object again. Granted this is all in the same system. The clients are different.
