but mine is Soap Instaed of File.

I get this message when running the interface end to end

Receiver service DEVCLNT200 cannot be converted into an ALE logical system

I have faced this many a times; every time the reason is different. and I read al most al of the threads related to it and applied evrything experts said. but I still have the error.

Thanks.
