Hi,

Your input column s having null value and that is the reason why it is giving below error.

Could you please try like below.

!Relational.ISNULL(row4.mycolumn)? (row4.mycolumn.equals("004")?"yes":"no" )
                                 :null

You can add all your conditions in the first part of your null check.

Warm Regards,
Nikhil Thampi
