Hi there, i have a Problem with my flow - the Data is not always the same but we want to use the same flow. Therefore I added two ways how the date will be prepared. But one way will always be empty and I would need to connect the outputs to the next node wit only one input. As it could be the case that the first way could not be executed i cant use the concatanate node… Here is a picture to see the problem I think my explainations are not that easy to follow :wink: [2024-09-10 16 17 36] Thanks and br Daniel

I try too with Try/Catch but with no success : I’m interesting for a possible solution ! Here is a suggestion with a test on the presence or not of Topic columns and two branches for processing (option 2 as @MartinDDDD and I explain earlier). It works : at least it produces something but is it what you are waiting for ? KNIME_exampleflow_suggest.knwf (49,7 Ko) Joel

I have 2 ways of data preparation - how can I merge them together if one way could not be executed
