Need help on manipulating an inbound message

[Chrisp7505]

We are receiving ORU messages from a vendor that need to be manipulated. The issue is that I need to modify the OBX segments and move them down 2 (renumber), so that I can insert two obx segments at the top of the obx section.

So
OBX|1|ST|CAOS&GDT|
OBX|2|ST|CAOS&GDT|
OBX|3|ST|CAOS&GDT|
OBX|4|ST|CAOS&GDT|
OBX|5|ST|CAOS&GDT|

Would become
OBX|3|ST|CAOS&GDT|
OBX|4|ST|CAOS&GDT|
OBX|5|ST|CAOS&GDT|
OBX|6|ST|CAOS&GDT|
OBX|7|ST|CAOS&GDT|

So that we could add
OBX|1|ST|CAOS&GDT|
OBX|2|ST|CAOS&GDT|

My code so far
I have the renumbering portion
var newOBXNum = 3;
for each (obx in tmp.OBX){
obx['OBX.1']['OBX.1.1'] = newOBXNum++;
}

My issue is trying to create the first two OBX segments with the values above
I tried using createSegement but it just overwrites.

createSegment ('OBX', tmp, 0);

Did you look at https://github.com/nextgenhealthcare/connect-examples/tree/master/Code%20Templates/Create%20and%20Insert%20Segment%20Templates ?

[Chrisp7505]

Thanks, I'll discuss it with the team and see about adding these functions. Is there anyway to do it without adding these functions?

[pacmano1]

You don't need to import the code templates - you can just paste the function into a transformer step of type javascript. I would functions for local use in a channel all over the place in mirth. Or just look at the function and do what it does.

Ok thanks I got halfway there.
I used this code and it inserted OBX|1| as expected.

var obx = ;
obx['OBX.1']['OBX.1.1'] = '1';
obx['OBX.2']['OBX.2.1'] = 'ST';
obx['OBX.3']['OBX.3.1'] = 'CAOS&GDT';
obx['OBX.4']['OBX.4.1'] = 'Test';
insertSegmentAfter(obx,tmp.OBR);

Now the question is how do I get OBX|2| ? When I used similar code as above OBX|2 overwrote OBX|1

Thanks for any help you can provide.

[Chrisp7505]

Nevermind I think I figured it out

[Chrisp7505]

Ok it works when I call the routine twice

var obx = ;
obx['OBX.1']['OBX.1.1'] = '2';
obx['OBX.2']['OBX.2.1'] = 'ST';
obx['OBX.3']['OBX.3.1'] = 'CAOS&GDT';
obx['OBX.4']['OBX.4.1'] = 'Test';
insertSegmentAfter(obx,tmp.OBR);

var obx = ;
obx['OBX.1']['OBX.1.1'] = '1';
obx['OBX.2']['OBX.2.1'] = 'ST';
obx['OBX.3']['OBX.3.1'] = 'CAOS&GDT';
obx['OBX.4']['OBX.4.1'] = 'Test';
insertSegmentAfter(obx,tmp.OBR);

Is there a "better" way of doing it?

[pacmano1]

The mirth forums has lots of stuff like this, e.g. https://forums.mirthproject.io/forum/mirth-connect/support/185695-adding-multiple-dg1-segments-after-the-obr

[Chrisp7505]

Thanks, I'll check there.

[Chrisp7505]

Thanks to your help, it is "almost" working, the only issue is that I need to wrap the text in OBX.5.1 between / .br/ any ideas?
Thus
obx['OBX.5']['OBX.5.1'] = /.br/'Sonographer '/.br/;

[Chrisp7505]

bah the slashes should be the other ones

[pacmano1]

Often to get the fastest help here - post a before and after message. And your code attempt in a code block (please use code blocks) Otherwise we are left guessing.

var text_to_add = ['stuff', 'stuff1', 'stuff2'];

for (var i = text_to_add.length - 1; i >= 0; i--) {
    var obx = <OBX>
        <OBX.1>1</OBX.1>
        <OBX.2>ST</OBX.2>
        <OBX.3>CAOS&amp;GDT</OBX.3>
        <OBX.5>{text_to_add[i]}</OBX.5>
    </OBX>;
    msg.OBX[0].parent().insertChildBefore(msg.OBX[0], obx);
}

for (var j = 0; j < msg.OBX.length(); j++) {
    msg.OBX[j]['OBX.1'] = (j + 1).toString();
}

This:

Another point here that there are multiple ways to do this.
