Exchanging information with Message Manager

You implement user-defined control numbering schemes through control number maps. When building envelopes for those application partners that provide partially wrapped X12 data, the compiled map providing the control number level and specified in the Partner Manager is executed by the RUN function.

The Message Manager passes input card 1 to the control number map the last used control number for this particular trading partner, application partner, or transaction set. The control number map returns the control number value to be used as output card 1 to the Message Manager; this value is placed in the appropriate EDI envelope.

This control number returned by the control number map is used to update the last used control number within the Message Manager for the appropriate trading partner, application partner, and transaction set.
