replace ~ with a –

The ~ is actually the repeating field delimiter (probably). You could do a concatenation in the xlate to get the desire results. Holler if you need more detail.

In HL7, fields can repeat. Do you see a ~ in MSH.02? If so, then the tilda is the repeating field delimiter.

ZFL|ONE^TWO^THREE~ABC^DEF^GHI|||||

So in the ZFL segment that I just made up, ZFL.01 repeats. ZFL.01(0) is “ONE^TWO^THREE” and ZFL.01(1) is “ABC^DEF^GHI”.

In your xlate, you can iterate over the field (OBR.44).

You probably need nested iterates: one for the group and one for the field. I could be wrong–I rarely use translations.

Normally OBR-44 is not a repeating field (probably why the receiving system needs the change).

Having said that, you will indeed need nested iterations. Also your basis for the OBR Group Iteration might be incorrect

Inside the OBR Iteration, you will need a field ITERATE for OBR-44.

Then inside that iteratin you will need a CONCAT that references the current occurrence of the OBR group AND the OBR-44 field as well as the outbound OBR-44 field (repetition 0 (1).

Something like this:

ITERATE – OBR Group
