Hi Friends,
I have a general question , Is there any performance or any other impact
if we use "THROW USER EXCEPTION MESSAGE" code frequently .
i mean If this code is getting executed every second, will it create any performance or another impact in the message flow . kindly share your valuable advice.
Thanks
Anil |

It depends...
Why not do some simple tests and think about it?
As you already have the ESQL to do it, it can't be that hard to run some tests with a flow that does it to say every other message. Then compare the elapsed time for processing 1000 messages to a flow that does not do it.
The reason I say, 'it depends' is because we have no, zero, nada, nilch idea of what happens in your flow when toy execute the ESQL to throw the exception.
Apart from that, and IMHO the fewer number of times you use that ESQL per day, the better.
There are other ways to signify a non fatal error that does not need an exception raised. But again, it all depends upon your site and their philosiphy for error handling.

I'm confused.
THROW USER EXCEPTION is used when, well, there was an error that occurs in your flow.
It's not clear what you would do with that error if you don't throw it. So how would the performance make a difference in how you code?
Do you want your flow to just stop because of some error, or produce an incorrect answer?
Or do you want to make sure the error is handled in the proper way for what you are trying to do?

I'm likewise confused.
The efficiency of an error reporting mechanism is usually not a consideration because in a well running system you don't call it that much. So why would you be calling it every second?
The performance impact is not so much the statement (generating an exception tree) but what it causes to happen. If (for example) you call it at the end of a medium sized flow then there's going to be a noticeable performance impact as the flow rolls back all the work it's done and resets the input. If it has to rollback a database as well, then that's more time.
But again, why the question?

Hi Friends,
Thanks for the reply, this questions arrived because of a change in the business requirement. usually user exception use to happen 5 to 10 times in a day , but now because of a issue in the external system ,
this user exception code will be called 2 to 3 times in a second . and as per the current business scenario this cannot be treated as a error or exception.
so we are planing to remove this exception throw method from the code.
