Creating Multiple DFT messages from single message with multiple FT1 segments

Question

I found the code below which does work except for segments after the FT1 segments.  At the bottom of my message is a GT1, IN1 and IN2 Segment.  There are 9 FT1 segments and the GT1, IN1 and IN2 only show up on the last message.

 

// 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();

You can save off the footer by finding the last FT1 group and then removing the FT1 segment.

 

// Get headers to use on all new messages
var headers = message.getNode('MSH[group=!FT1]');

//Retrieve the FT1 Segments
var ft1Groups = message.getAllNodes('FT1');

var footers = message.getAllNodes('FT1[group=!FT1]');
var foosterLength = footers.length - 1;
footers = qie.parseHL7String(footers[foosterLength]);
var extraFt1 = footers.getNode('FT1');
footers = StringUtils.replace(footers, extraFt1, '');

//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] + footers);

   //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();

Thank you.  This works except for each FT1 there is a ZFT segment, which I forgot to mention.  After running the code above I get the last ZFT segment in each message rather than the matching ZFT segment with the FT1 segment.  Hope this makes sense and sorry for any confussion.

I just figured it out.  Thanks for your help
