my file has two tabs, “Input” and “Periods”.
I want to attach the “Wished Resulut” field from the Periods tab to the “Input” tab.
The criterion should be
- The date (Date KNIME)
- Month 2
I expect that after the joiner node the same amount of data will be contained in the table as at the beginning. Why is this not the case?

Hi @ARock1980 ,
it’s because you are doing a inner join. The missing 5k rows have no correspondence with the right table. It happens with Month 2 = “PY”.
If you test the lenght of “PY” in the second table, it is 3 char long (see below):
After cleaning white spaces, everything seems to work as desired. You can replace the column after using function “stripEnd()”.
Have a nice day,
