Hello
as we run into same problem using output type 'A' (ALE) we do use output type '6' (EDI). But still your EDI partner can be a logical system with EDI partner role LS. And if you choose so the logical system (CMESWBDO), IDOC message and output type must be maintained in the partner profile.
The logical system with partner role LS can be maintained as fixed partner in your output message master data. MN25 for inbound delivery output.
The error message you mention above looks like missing (or incorrect) partner profile. That will also prevent message determination in VL32N. Be aware that the partner in partner profile is logical system (CMESWBDO) with partner type LS (Logical system). But because you are using EDI next to partner type also partner role LS should be used.
