How do I split a DFT message with multiple FT1 segments into one DFT per FT1

Question

CB can only accept 1 FT1 segment per DFT message.  So we are needing to create one message per FT1 segment.  How would I go about doing this?

How would I split this message into four DFT messages:

Answer 1

This can be accomplished with a custom mapping using the code below.

 

// Get headers to use on all new messages

var headers = message.getNode('MSH[group=!FT1]');

//Retrieve the FT1 Segments

var ft1Groups = message.getAllNodes('FT1[group=!FT1]');

//Loop Through Each one

for (var i=0 ; i < ft1Groups.length ; i++) {

   //Set newMessage to the headers and the individual FT1 Segment

   var newMessage = qie.parseHL7String(headers + ft1Groups[i]);

   //Reset FT1-1 to "1"

   newMessage.setNode('FT1-1', '1');

   //  Ensure we have a unique id in MSH-10 (message ID)

   //  so the messages don't error out in the receiving system

   newMessage.setNode('MSH-10', newMessage.getNode('MSH-10') + '-' + i);

   // Send the new message through to the remaining nodes

   qie.spawnNewMessage(newMessage);

}

//Discard original message as it is no longer needed.

message.discard();

After this mapping function, you will need to create a new mapping node for any additional mapping functions. Most cases you will not use source.getNode after a spawn. Use message.getNode in mappings that follow the spawn.
