Replacing Missing Value in Column

Hi ,
I am new to KNIME , can someone help me how do I replace missing value with pre-defined text.
I have column with two binary values viz. “Yes” and “No” , but there are many cells in the column with blanks.
I would like to replace these blanks cells with “No”.

Thanks in Advance

The missing value node(s) is your friend


Thanks ! That worked.
