Using CLv19, In order to delete a segment using an Xlate you would use the PATHCOPY @null approach. For example, to delete a PV1 segment you would do the following:
<pre>Action: PATHCOPY
Source: @null
Destination: 0(0).PV1(0)
Result: PV1 segment deleted</pre>
Unfortunately, this method does not work when attempting to delete the second FT1 in a message. What am I doing wrong?
<pre>Action: PATHCOPY
Source: @null
Destination: 1(1).FT1(0)
Result: All FT1 fields are deleted but FT1 segment header remains.</pre>

1(1).FT1(0)
The trailing (0) is the iteration of the segment in this case. The 0 means the 1st iteration, it’s hardcoded.
So, try this instead: 1(1).FT1
That would get rid of all FT 1 segments.
If you are looping and want to get ride of specific segments only, the use an iteration variable like (%s1) and 1(1).FT1(%s1)

If you were to run the testing tool using HL7 Test with the variant used in the XLate, how would it display the paths you would like to delete? Also if you delete a required segment in a group like {OBX [{NTE}]} deleting the OBX and an NTE exists, the outbound variant will enforce the need to have the OBX segment even if it is blank or a stub. Are there other Segments with your FT1 segment? The pathcopy is very powerful in that pathcopy @null –> 1 will delete all segments where the path begins with 1.
Can you consider only building the FT1 group based on a condition? Are you only deleting the second instance?
There are several ways to get rid of the FT1 stub, however not sure I would recommend just deleting the FT1 segment if other segments are associated with it.
Hope this helps some….

Is the case you have more than 2 FT1 Groups (FT1 is almost always a Group) and you want to get rid of just the second FT1 Group.
Or do you want to get rid of all of the FT1 Groups?
I suspect because you are doing things this way there is a BULKCOPY involved – is there?

Thank you all for your input. Very helpful.
Jim, Yes, I am using BULKCOPY. I only want to delete the second group. (The Second FT1 Group). Good question.
Keith, Your question prompted me to look at the complete path. That was one of my issues. I was not referencing the path correctly.
James, Your input helped me resolve my issue. Once I created a new variant with an optional FT1, I was able to move forward.
Max, Thank you for the Path information. That helped me work toward the solution.
Solution:
- Use a variant to make the FT1 optional. Otherwise, it will keep adding the blank FT1.
- Make sure you use the right path when referencing the segment you want to delete.

Todd,
Just so you know, this could be done without changing the variant.
With the FT1 Group Required (per the standard) and a BULKCOPY in place, one could do a PATHCOPY to null all FT1 groups then ITERATE over the IB PATHCOPYng only the Groups wanted.
This way, the next person does not need to be aware the FT1 Group is defined non-standard for the OB and moreover, should the variant need to be used by others, they could rely on the structure being standard.
if no BULKCOPY, then ITERATE and PATHCOPY only the groups wanted.
Just another option…
