Hi All,

I have done a change to design of message flows. Previously we used to have multiple compute nodes for each target system. But this design creates multiple copies of messages and sends it to each compute node hence it is not effificent from performance point of view. As part of new design I converted each compute node ESQL into a Function. Now I just have one compute node and I call functions one after the other. I use PROPAGATE in each function to propagate messages from each function to the required target system.

The question I have is regarding Error handling. Since it is more of sequential processing now, if the first Function in compute gets an error in transforming will the processing still continue with rest of functions or the message will just roll back for all of them and not go to any of them?
I am returning a boolean for the function. The environment is message broker 5.0 CSD3.

Regards

Kiran

If you have set your output nodes under transaction you will have rollback for all. The processing will not continue. You have to use try/catch or connect failure terminals in your propagation flow.
