Looping through repetitive HL7 segment groups in business rule

Hi,

we get HL7 ORU messages from a laboratory system. Messages that do not contain an observation date should not be forwarded to the business operation. My problem is that the observation date can be in any repetition of the ORCgrp. How can I loop through the ORCgrps in a business rule?

Regards

Robert

I already tried the asterisk:

Length(HL7.{PIDgrpgrp(1).ORCgrp(*).OBR:7.1})>0

... and the syntax with the square brackets:

Length(HL7.[OBR:7.1])>0

Hi, you might be looking for foreach action:

And an upgrade, since the foreach action didn't exist in 2017.2 😉

This should work (no looping required):

I'm using the parenthesis syntax with the Matches() function to locate a pattern of any number of punctuation characters (.P) followed by 8 numeric characters (8N) followed by any number of any character (.E).

The parenthesis syntax returns the repeating values in the form "<><><20230512191543><>" where <> represents an empty iteration of the repeating field (and fortunately qualifies as a punctuation character).
