Hi @SimonS
Thank you for your reply.
I collected some experience and made some decisions in the period after I had created this topic.
More specifically, I moved the way I design my workflows a bit from nested workflows which means those workflows invoked by Call [Local] Workflow nodes placed in another (outer) workflows. This concept stopped suiting me after I had learnt an investigation of problems in these nested workflows is pretty inconvenient because nested workflows don’t produce output I could import to KNIME Analytics Platform IDE the way I could do it in case of directly (using batch mode) invoked workflows.
I created a topic Batch Mode & Call Local Workflow - where is nested workflow output? which deals with the issue I just described. Unfortunately, we started a slightly of-topic conversation in the issue shortly after I had created it, so my questlion I asked there is still open.
Regards, Jan
