How to Limit Repeative HL7 Field in Xlate mapping

[Raj]

I Am trying to limit  DG1 segment coming from HL7 message to only 3 repeats if the original one has more than 3 DG1 segments info   and  can this be done using Iterate or by tcl not sure  how i can get this mapped.

Any Help or suggestion will be of great help.

Have you tried something like this?  I don’t have access to a licensed system so I can’t test it right this second…

Set your iterate up as list.

Type: List

Basis: 0 1 2

Variable: %l1

This should get you what you want.   I have tested it in an xlate and it works.

Thanks…

You can also just use the if statement against the iteration variable.

If $%s1 < =3

pathcopy your %s1 segment

This would copy 0 1 and 2 of cours e with the proper syntax….
