Hi All experts out there….. i need help, i am trying to use pathcopy to get rid of the OBX segment but I do not seem to be able to get rid of the word “OBX” in the segment
say for example
My input is below
ORC|1|….|
OBR|1| ……|
OBX|1|123|this is testing
OBX|2|124| This is second one
My output will be omitting the OBX after plucking in some value from the OBX segment….
ORC |1|
OBR|1|…|this is testing
How can i achieve this using pathcopy? I am using iterate for segment OBX…and within the iterate, i have IF condition to check..
a pathcopy to copy @null to 2(%g1).1(%g2).1(0).0(%g3).OBX(%s1)
My output is as shown below, this is not what i want,
ORC|1|…
OBR|1|…|this is testing
OBX
OBX
My desirable output is
ORC|1|..
OBR|1|…|this is testing
HELP!!!!
Thanks millions

If it is not the optional setting on you outbound variant, try shortening the path of the OBX from 2(%g1).1(%g2).1(0).0(%g3).OBX(%s1) to 2(%g1).1(%g2).1(0).0(%g3).OBX The pathcopy statement will use as much of the path as you provide. So if your goal is to eliminate all OBX segments based on an IF condition you might try this without the iterate for the OBX. Hope this helps….. One more thing if you want to eliniate both the OBX and NTE or AKA %g3, if you shorten the path to 2(%g1).1(%g2).1(0).0(%g3), this would eliminate all segments in %g3 group by pathcopying @null to it.

Typically the OBX segment repeats as part of a group. In most cases this group would be your %g3 group or the third group iterate that you define. If this is structured as an ORU type message, your groups will generally be constructed like:
MSH
…
{ # Opens repeating PID Group
PID # %g1
{ # Opens repeating ORC Group
ORC # %g2
{ # Opens repeating OBX Group
OBX # %g3 Note OBX repeats as part of Group, not a segment.
[{NTE}]
} # Closes Repeating OBX Group
} # Closes repeating ORC Group
} # Closes repeating PID Group
Notice above the OBX does not directly have the {} around it signifying that it repeats, but the Group does. Also since [] are not present, this means it is required.
In this case, the segment OBX only repeats as part of a group. Also as you develop each nested basis, the previous %g1, %g2, etc. must be included in the basis. You may want to review the variant of your outbound, highlight in your HL7 variant tool the ‘{‘ where the OBX group begins and make it optional. This would add Braces around both OBX and NTE. The result you are getting is very characteristic of the OBX segment on th eoutbound variant being required.
