If your sender is sending Edi document as attachment then they should set content-type as “application/EDI” while sending to your wM server and the dedicated service input variable should be ediByteArray (case sensitive).
and if it is xml attachment then content-type is “text/xml”,so that webMethods server can read and process the request to appropriate service input.
During this invocation pls do keep savepipeline and restorepipeline in the target service for debugging,and may also use debuglog service for more tracing…
HTH.
