Hi @MartinViking
Why would not not also create the delivery delivery template where the retry is already set to 0?
Otherwise, you have plenty of typology of type control you can inspire yourself to get the code to set the retry to the value you wish.
The syntax would be something like
if( delivery.messageType == 143)
delivery.execution.maxRetry = 0;
You would activate this rules on the channel (messageType) 143 too
Wave Scheduling Typology Rules for sample of syntax
Hope this helps,
Thanks
