Want to stop execution of a workflow if certain condition doesn't match

[mlauber71]

@tamzid89 one way I would do this is use the

Empty Table Switch

or if it is indeed just the incoming data try use

Breakpoint

Also a construct with a CASE Switch Start – KNIME Community Hub could work.

Maybe you start by constructing a sample workflow that would represent your case. Would this workflow do something else besides stopping. Could a loop be involved? Are there other branches in the workflow that might need handling?

Stop my loop if the column sum is greater than 50% of my flow variable

@kowisoft it could look something like this. Collection the iterating values in a temporary file and appending that at each step of the loop. And then like you have already done collect the sum of the column and then make a decision to sop (or not). Maybe not the most elegant way… Just make sure to reset the temporary file. One could also automate that by using a switch catching the first iteration of the loop (I have and example of that somewhere). [image] [image]
