yes you can with a few limitations. Being that there may not be a previous op, you may return a null value. You have to use a inner sub query and that will limit you to returning only one column. If you need multiple columns with this method you may just have to make more than one query. This is the only method i know of at this time, I’m sure there may be other methods.
create a inner sub query
bring in the joboper table (you’ll need to assign an alias), create links under subquery criteria tab.
bring in oprseq column
sort desc
back in your top level query create a calculated field based on the datatype returned from your inner sub. Place the subquery in the expression. Should be good to go at that point…
