Just an update I have tried the following however, the MSH segment seems to be getting overwritten, any ideas why?

s tMsg = ##class(EnsLib.HL7.Message).%New()
s tMsg.DocType ="2.3.1:DFT_P03"
s tSeg = ##class(EnsLib.HL7.Segment).%New()
set tSeg.DocType="2.3.1:PID"
s tsc = tMsg.SetValueAt("abc","MSH:9")
s tsc = tSeg.SetValueAt("PID","1")
s tsc = tSeg.SetValueAt("TEST","3.1")
set tsc=tMsg.SetSegmentAt(tSeg,2)
w tMsg.OutputToString()

I have also tried set tsc=  tMsg.AppendSegment(tSeg) which seems to be overwriting the MSH segment.

Any help would be great.

Hi Suman,

Thank you for your reply, do you have any sample code for this?

Hi Katherine,

Thank you for your prompt reply in our version of Healthcare I don't see the option for Authorization Instance ID  do you happen to know why this is would be the case and is this required?

Kind Regards,
