Iteration Nightmare

[Gina Borden]

I am trying to format an ORU from Pyramis to McKesson HPF.

The Pyramis specs state on the 4th iteration of the OBX field 5 is repeating.

I thought I understood iterations, but I have tried for 2 days to make this work, and I can’t seem to get it.

I am only getting the first line of field 5 on the 4th iteration.

I am going to try to attach the xlate and sample message, and any help would be appreciated.

Do you need to specificall clear the first 4 iterations of OBX:5 from the iteration at the group level?  Also it appears as though you have treated the repeating groups at the top of your iterate and then started using the %f1 variable further on down.

I would need to know the structure of your variants in and out to take this further…

ie

MSH

EVN

PID

{

   [{OBX}]

    [NTE]

}….

This is my inbound variant

{

 [

    PID

    [PD1]

    [{NTE}]

    [

       PV1

       [PV2]

    ]

  ]

  {

    [ORC]

    OBR

    [{NTE}]

    {

       [OBX]

       [{NTE}]

     }

    [{CTI}]

  }

}

This is the OBX segment of the specs:
