string manipulation

Good morning people, everything fine ?

I would like to create a column where it tells me what is different from empty compared to the columns VUC, medion3/4, cart, truck. can you help me?

Hi @Gabriel2020 ,

You will need a library to say what kind is any data that you have.

Example: What define me a toco, carreta and truck value? The medio column? If does, you can use a cell replacer or rule engine to ser a column for you.

If you can put a workflow example here, will be better too.

I think I didn’t make it clear, but below is the workflow. each originxdestination needs to have 5 type of vehicle, which are the ones that it includes as a column.
