Can I renumber segments in a HL7 message

Question

I have FT1 or OBX segements I modified or removed. Can I update the first field in the segment to put them in order.

Answer 1

To reorder segments use the following code in a custom mapping:

 

// What segment should we reorder

var segment = 'OBX'; //Set this to OBX, FT1...)

 

// Get count of segments

var segmentCount = message.getCount(segment);

 

//Update the first field for each segment

for (var i=1 ; i <= segmentCount ; i++) {

   message.setNode(segment + '-1', '' + i, i);

}
