Hopefully someone won’t mind helping a Cloverleaf noob out. I want a message killed if a certain set of criteria are met. From what I’ve gathered returning KILL $mh is the way to do this. So I have a couple questions in regards to this.
1. Can this command be used in a TCL fragment inside the XLATE itself, or does it need to be in a TCLPROC?
2. Does KILL $mh need to be placed in the message itself? if so is one location better than another.
Thanks for any input.

Keith, Use KILL $mh in TPS scripts. The best location is your inbound TPS so that the message doesn’t get to the xlate. If possible always filter your unwanted messages as early as possible in the message flow.
You wouldn’t use KILL $mh in an xlate.

Keith, You can filter messages within the Xlate – however many of us (myself included) do not believe it is the best place (if you want to have a more in depth discussion about that, email me).
You can place your Tps type Tcl proc at the inbound Tps UPoC – however that means that filtering is effective for EVERY receiving system. That may be OK but, in my experience, much of the message filtering is specific to the destination.
So you can move down stream to the TrxId UPoC and apply your filter there. That gives more tactical control over the effect of the filter.
You can also place your filtering proc at the pre (xlate, raw) message routing UPoC. This is my preference because now I can have the greatest granularity of control and yet remove messages before too much engine work is done.

Jim’s explanation is right on the money. Try the attached proc – I use it extensively on route upocs… It’s simple, and easy to provide arguments for. -

Jim, You mention trxid as a possible place to kill a message – I thought message data in a trxid was immutable?

Garry, What you do is change the Transaction ID to something like ‘Del_filt1″; then in the Route, do a tpsmsgkill on the route for messages with that TrxID.

I have used Jim’s tps_msg_action.tcl proc for killing messages pre-xlate which has been great for quick one or 2 conditions. I too have found using a trxID proc for identifying messages to be killed to be more flexible, consice, and maintainable.
As pointed out already the trxID proc only returns a trxID which in turn can be set to something usefull like trxId_KILL to identify messages to be killed in the route via hcitpsmsgkill.
Here is an example of a trxID proc I did for our pharmacy system and some screen shots showing how to use it:
trxid_SIU_rxtfc.tclCode:# Begin Module Header ==========================================================
#
# —–
# Name:
# —–
#
# trxid_SIU_rxtfc.tcl
#
# ——–
# Purpose:
# ——–
#
# Set the trxId to the message type in MSH-9 as the default case first.
#
# Set the trxId for SIU_S15 messages to one of the following:
#
# – SIU_S15_==arrival
# which means that ZSD-2 == “SC165”
#
# – SIU_S15_!=arrival
# which means that ZSD-2 != “SC165”
#
# For SIU* messages set the trxId to “trxId_KILL” if one of the following SIU filtering conditions are met:
#
# – trxId_KILL if the message does not have a MRN, which means:
# PID-3.1 is empty
#
# – trxId_KILL if the message does not have a patient account/visit number, which means:
# PID-18.1 is empty
#
# – trxId_KILL if the message has an undesirable location, which means:
# AIL-3.1 does NOT match an entry in lookup table rxtfc_desirable_locations_for_all_SIU
#
# – trxId_KILL if the message account/visit number starts with “20”, which means:
# PID-18.1 first 2 characters = “20”
#
# – trxId_KILL if the message account/visit number starts with “90” and patient type is “O”, which means:
# PID-18.1 first 2 characters = “90”
# and
# PV1-2 = “O”
#
# – trxId_KILL if the message account/visit number starts with “90” and has an undesired location, which means:
# PID-18.1 fist 2 characters = “90”
# and
# AIL-3.1 does NOT match an entry in lookup table rxtfc_desirable_locations_for_90_SIU
#
# – trxId_KILL if the message is too old, which means:
# AIL-6 is a valid date/time in a ts format
# and
# AIL-6 is older than -6 hours

Hi, Never thought about doing it that way. I usually just have a KILL TPS that I add in to my inbound TPS routines.
This makes sense and I will look into adopting it in future builds.
Thanks
Garry
