Functional ID

The data standard used determines the functional ID or message type found in the data. For example, for the ANSI X12 and the UCS standards, the functional ID is taken from the functional group header segment of the data. In addition, for the UN/EDIFACT and TRADACOMS standards, the functional ID represents the message type. The following table contains the location of functional IDs identifying the group or message type:
