In the tMap component, where do you set up a filter on the input fields?

The tMap component allows you to set up a filter on the input fields by using the Expression filter in

the output table. The Expression filter is a field where you can enter a logical expression that

evaluates to true or false for each input row. For example, if you want to filter out the rows that have

null values in a certain column, you can use row1.column != null as the expression filter for that

output. The expression filter applies to all the input fields of the row, not just a single column. You

cannot set up a filter on the input fields by using the Match Model parameter field for one of the

inputs or outputs, as this field is used to define how to match rows between different inputs or

outputs based on a key attribute. Reference: Talend Open Studio: Open-source ETL and Free Data
