Need to evaluate rule based upon the content of "Z" segment, and only process if it exists on a table.

#Business Rules #HL7 #InterSystems IRIS for Health

Receiving HL7 messages from our EMR, and processing to send out to downstream system. These are SIU_S12 messages, with a custom ZOR segment added by the EMR to include order information. The purpose of including this segment is to allow us to only send messages to the vendor that contain a procedure ID that is included on the list of procedures desired by the vendor. These values are in a LUT with the procedure ID in the key field, and a value of 1.

We are recently upgraded to 2023, so I'm strugging with two things: the new look of the rule editor, and the exist expression to validate that the contents of ZOR:3.1 match a value on the table.

Rule so far (I previously tried with HL7.{ )

Thanks in advance!

The first parameter (Lookup Table Name) of Exists function must be quoted: Exists("HologicProcedureFilter",.....)

If you want, you can switch to the old zen based rule editor, in the upper right of the page click on the user icon and select Open in Zen rule editor:

Note that it will open the rule in new tab, leaving the old tab open, make sure you use only one tab to edit the rule!

Thank you! After lunch and with fresh eyes I found our problem was that the Data structure was not designated for the subsegments of ZOR-3, so the Lookup needed to either be looking for the entire contents of ZOR-3, or the data structure defined. We went with defining the data structure.

The table in Exists needs to have " " around it as it is still a string.
