| # EDI message levels and file layouts Conversion setups specify the relationships between the levels that represent the different sections of the EDI message (overhead, header, line, and footer). If the corresponding message has a Multiple file layout - which indicates that the data in the message is split across multiple ASCII files - each level corresponds to a unique ASCII file. If the corresponding message has a Single file layout - which indicates that the data in the message is received in a single ASCII file - each level corresponds to a unique level identification. For incoming messages, the level identification is specified in the Conversion Setups (Relationships) (ecedi5112m000) session; for outgoing messages, you can define the level identification in the conversion setup definitions. Relationship sets are required in order for ERP to: Select and read the correct file(s) in the EDI Interchange Controller (ecedi7210m000) session (incoming messages) Generate the correct ASCII files in the Generate EDI Messages (ecedi7201m000) session (outgoing messages) |
