You can specify pipeline variables that must be present in inbound documents to match the document type. Criteria for matching inbound documents to the document type are name/value pairs, where values are optional. If you do not specify a value, the document matches the document type if the pipeline has a variable that matches the specified name, regardless of the variable’s value. If you specify a value, the variable must have the specified value. The variables are inserted into the pipeline by the service that sends the document to Trading Networks.

To add a pipeline variable, click Add in the Pipeline Matching panel on the right. In the Add Pipeline Variable dialog box, type the variable name and optionally, the value.
