Module for EDI maintains information about control numbers in the EDIControlNumber table, which is a Module for EDI-specific table in the Trading Networks database.

For ANSI X12 and UN/EDIFACT documents, when you create services to form outbound EDI documents, you can invoke the following services that are provided with Module for EDI to add group and interchange headers to the outbound EDI document:

When invoking one of the above services to add a header, use the ctlFromTable or grpCtlNumber input parameter to indicate whether you want to use the control numbers from the EDIControlNumber table for group and interchange headers. If the EDIControlNumber table does not have an entry for the group or interchange sender/receiver pair, a row is added to the table for the sender/receiver pair and the control number is set to 1.

You can set the initial values you want to use for sender/receiver pairs using the Module for EDI home page. For instructions, see Configuring Control Number Settings.
