Using the Filter Transform
You can use the Filter Transform to filter any unwanted HL7 messages out of the incoming feed before they are passed to the next device in the channel. For example, you may want to filter out messages if a specific field contains a certain value.

You can perform more complex filtering using the C# Transformer. |
Click the Add Filter Transform button. In the Path column, enter the field you want to check (e.g., MSH-3). Click the icon to launch the popup window.
Enter the value that should be matched to the incoming message (the Filter Message).
By default, filters are "false." That is, if the Filter Message value does not match the incoming field value, the message will be filtered out. If desired, Connexion can mark this as an error (check the Mark as Error box on the popup).
Once the Filter Transform has been added and configured, set the Condition and add an optional Description.
