Process only record where a specific value is found

I need to process (read side) only the records with a specific field value: when this value is found (i.e. "5"), then the record cointaing the field "5" must be passed to the write side.
How can I do with flowheater? Thank you.


See, please, the attched file for an exmaple input file

For this you have to move one If-Then-Else Heater and one Filter Heater on the Designer. Connect the certain field with the If-Then-Else Heater. The Output from the If-Then-Else Heater you have to connect to the Filter Heater.

After that double click the If-Then-Else Heater and enter your condition. If you want to pass all rows with the value 5 you have to use the condition

!= 5

Is the value of the certain field = 5 In this case the If-Then-Else Heater returns false to the Filter Heater and the row are not filtered. In other cases (value <> 5) the If-Then-Else Heater returns true = the given row are filtered.
