Hi everyone,

I would like to use a variable in a xlate destination of the “Output Message Format” to address a repeating OBX field.

I set successfully the variable with a “Copy” operation.

But when I try to use the variable in the destination statement the variable will not used correctly and the variable will be “replaced” with 0.

My try: 1(0).1(0).3(@obxNum).0(0).OBX(0).#1(0)

Current result: 1(0).1(0).3(0).0(0).OBX(0).#1(0)

Expected result: 1(0).1(0).3(3).0(0).OBX(0).#1(0)

Thanks for any hint/solution to get the expected result.

Best regards
Creator

  For iterations and variables used in the HL7 path use a % variable. For example, use %s9 or %s99, your choice. You can reference and manipulate this variable by using the notation $%s9.
  
  I tend to use a Math Add
  
  Source
  
  $%s9
  
  =1
  
  Destination
  
  $%s9
  
  to increment
  
  Use %s9 in your path
  
  1(0).1(0).3(%s9).0(0).OBX(0).#1(0)
  
  You should be able to use this to control your outbound path and counter…
  
  Copy
  
  Source
  
  $%s9
  
  Destination
  
  1(0).1(0).3(%s9).0(0).OBX(0).#1(0)
  
  Hope this helps… Your iteration variable on your source side should remain as you defined it in the iteration command.
