During inbound processing, Module for EDI can validate the interchange and/or group control numbers (or TRADACOMS transmission and/or batch control numbers) in the headers of the inbound EDI document. Validation determines whether the control numbers are in order, and therefore whether the EDI documents arrived in order.

To determine whether a control number is valid or invalid, Module for EDI looks up the EDIControlNumber table entry that corresponds to the interchange or group header (or transmission or batch header) of an inbound EDI document. It then compares the control number from the header to the next expected control number in the EDIControlNumber table entry to determine whether the control number is valid or invalid.

For more information about the EDIControlNumber table, see Managing Control Number Information.
