EDIFACT outbound trade links

Edit online

Trade links can be added, changed, or deleted. In addition, existing Trade Links can have their individual Messages (also known as Documents or Groups) added, changed, or deleted.

To add a new EDIFACT Outbound trade link, use the tags EDFOBTPLink, EDFOBAPLink, and EDFOBMsgLink. To change an existing EDIFACT Outbound Trade Link, use the tags EDFOBTPLinkChange, EDFOBAPLinkChange, and EDFOBMsgLinkAddChangeDelete. To delete an entire EDIFACT Outbound Trade Link, use EDFOBTLDelete.

EDIFACT Outbound Trade Links are very similar to Inbound Trade Links. The main difference is no Unknown Outbound Trade Links. All Post Offices are defined at the Message level. Applications are specified in the tag EDFOBMsgLink when adding, or EDFOBMsgLinkAddChangeDelete tag when changing.

Trading/Application Partners must previously exist in the database for the Trade Link to be added. As with Inbound Trade Links, Application Partners may or may not be specified, depending on the setting of MandatoryUNG. Application Partners, if required, are specified within the EDFOBAPLink or EDFOBAPLinkChange tags, and must "belong" to the Trading Partner specified in the EDFOBTPLink/EDFOBTPLinkChange tag. Application Partners can only be specified if the MandatoryUNG field is set to O (optional) or M (mandatory).

Applications are nested within the Trade Link record when there is no UNG level; otherwise Applications are nested within the Application Partner record. The same Application cannot appear more than once within a Trade Link. The following table, field, and tag descriptions are for EDIFACT outbound trade links:
