Hi

As per my knowledge webMethods Provides the WMEDI, WMEDIForTN and WMEDIINT for EDI Process. But for Tradacoms Solutions only One WMTradcoms package is available, I want know all above three packages solutions are embed in wmTradcoms package or I have use separately WMEDIINT and WMEDITForTN as per requirement. Please explain?
