Hi,
Could anyone help me with my issue?
I have one big sheet of Excel with data let's call it "A" ( there are some information concerning customers e.x Name, Surname, address, client number and so on).
I also have small data of another Excel sheet let's call it "B" and here are some customers that may or may not be included in this first sheet.
Now I have to get rig of customers that are included in Excel sheet ( B ) from the Excel sheet ( A ) in other words delete them.
The outcome of this process should be A - B.
How can I do it with Knime.
I tried with Joiner but I have to do something wrong or this is wrong idea.
