I figured it out on my own. 

It did not like

<assign value='source.GetFieldStreamRaw(.tStream,"ORCgrp(1).OBRgrp(1).OBXgrp(k1).OBX:ObservationValue(1).AlternateText}",tRemainder)' property='tSC' action='set' />
 

I had to change it to 

<assign value='source.GetFieldStreamRaw(.tStream,"ORCgrp(1).OBRgrp(1).OBXgrp("_k1_").OBX:5.5",.tRemainder)property='tSC' action='set' />

I should of explained this a bit better.

We have 3 servers, 2 (A,B) Locally, 1 (C) offsite.

Currently we are running on Server B. If I do a backup of Server B on 2015.2.2, can I restore it on Server C after it has been upgraded to 2019.1. 

I was wondering if the Full System Backups were compatible across versions of Health Share/Health Connect, since 2019.1 everything changed from ccontrol to iris.

I thought I would give this a shot before bugging WRC, but I'll go ahead and ask them.

Thanks

What do you mean by "After that you need to create an instance of this class and add it to HeaderOut property of your WS client."

I created the custom header as suggested above

Class osuwmc.Epic.CustomHeader Extends %SOAP.Header
{

Parameter XMLFORMAT = "literal";

Parameter XMLIGNORENULL = "RUNTIME";

Parameter NAMESPACE = "urn:epic-com.2013.Interconnect.Headers";

Parameter XMLTYPE = "Epic-Client-ID";

Property Value As %String(MAXLEN = 36, XMLPROJECTION = "CONTENT") [ InitialExpression = "12349fe5-2ff8-4b79-b723-e69efbabcdef" ];

}
 

then in my operation I did the following...

Method AddCustomHeaderElement(mustUnderstand = 0)
{
set h=##class(osuwmc.Epic.CustomHeader).%New()
if mustUnderstand{set h.mustUnderstand = 1}
Do ..HeadersOut.SetAt(h,"osuwmc.Epic.CustomHeader")
}
 

but still got an error on HeadersOut.

What is HeadersOut and where do I set it?
