kill message in translation / suppress

To me, the wording in the documentation is confusing.  SUPPRESS in a translate will prevent the message from going beyond the translation process.  It will still process the message through the translate so any coding you have will still be done (an email for example), but the message will not be sent to the output after the translate.

To prevent a message from being translated, you can use a proc in either the Inbound/TPS Inbound Data UPOC which prevents the message from getting to any routing, or you can use Pre Procs UPOC on the Xlate routing setup which will be only for that particular route.

The way I like to use SUPPRESS to filter messages is to use an IF  with ELSE Action:

IF <cond>

SUPPRESS

ELSE

Build the OB message…

This way the Xlate tokenizes the OB message but does not populate anything IF the filter condition is true.

If you are receiving duplicate OB messages, then I suspect you have a CONTINUE or SEND Action being executed.

I had a situation where the requirement was to do a lot of filtering and it was required to be in Xlate. In that case I used specific Xlate(s) for filtering, named them appropriately so one could tell which Xlates filtered and chained them in front of the Xlates which were needed to build unfiltered messages.

That worked quite well. I did not detect any significant performance issues.

Why would you want to incur the overhead of translation if you will KILL the message within the Xlate?  Translation is the long pole in the overall message processing path.   As Paul said, write a filter pre-proc and kill before Xlate.  There are probably exceptions, but will be rare.

Just another perspective, IF you’re receiving multiple messages from an xlate it is likely because you’re using CONTINUE off an iterate.

If you are qualifying a message off of values within a repeating group/segment (which would be difficult from a pre-proc), then you could use a garbage variable such as “@sendFlag”.  Populate @sendFlag with NO before the iterate. Populate the variable with something else (YES) if the condition is met.  Then CONTINUE if that variable is not NO.  This way you will only have a true or false condition rather than multiple CONTINUES of a message within an iterate.
