I need to create a step which filters the records based on the first occurrence of a column.

Hi Mark,
If I understood your question....

DQ Tutorial is the best place to start playing with it. Section 05.03 is about using Filters. It does give a simple example and you can use more complex things using expressions.

Press Control key and space tab on your keyboard to see more of these complex functions and its syntax, usage etc.

this might help you..
//src_province = 'ON'
substr(src_province,0,1) is 'O'

Hope this helps,
Regards,
