How to remove few OBX segments based on <if Condition> and reset OBX SETID sequence
JamesG
Graham, Ben
James,
The key is to use a variable that is incremented each time you create a new OBX, using this value to populate the OBX set id (field 1), and as the iteration instance of the target OBX
<assign property='ObxResultInstance' value='"0"' action='set'/>
<foreach property='source.{PIDgrpgrp(1).ORCgrp(1).OBXgrp()}' key='k1'>
<if condition='source.{PIDgrpgrp(1).ORCgrp(1).OBXgrp(k1):2}=”TX”’>
<true>
<assign property='ObxResultInstance' value='ObxResultInstance+1' action='set'>
<annotation>Creating a new OBX, increment OBX instance</annotation>
</assign>
<assign property='target.{PIDgrpgrp(1).ORCgrp(1).OBXgrp('ObxResultInstance).SetIDOBX}' value=’ObxResultInstance’' action='set'/>
<assign property='target.{PIDgrpgrp(1).ORCgrp(1).OBXgrp('ObxResultInstance).OBX:ObservationValue()}' value='source.{PIDgrpgrp(1).ORCgrp(1).OBXgrp(k1).OBX:ObservationValue()}' action='set'/>
</true>
</if>
</foreach>

I would need to see your transform to answer definitively, but some things you can look at...
Every time you create an OBX you are incrementing the instance counter ObxResultInstance.
Assign this value to the set id field (i.e. <assign property='target.{PIDgrpgrp(1).ORCgrp(1).OBXgrp('ObxResultInstance).SetIDOBX}' value=’ObxResultInstance’' action='set'/>).
Make sure you are not overwriting the set id later in the transform.
Also, make sure you only increment the instance just before you create an OBX segment.
One other possibility is that you are incrementing the instance counter incorrectly...

Subject: [InterSystems-EnsHlth] How to remove few OBX segments based on <if Condition> and reset OBX SETID sequence
Hi
I need some example of DTL whereby I can remove OBX segment(s) based on <if condition> from ORM^O01 message and make sure that output has correct OBX sequence (SETIDs).
Apologies this might be basic for many but I am an Ensemble beginner.
Thanks,
James
