Hi,

I have a custom task defined, that will process a list of users(An array of users return by SQL query).

The custom task uses Workflow Job ID "18114:WPDS", where does this information stored in AVUSER ?

Q1) What is the SQL query that i can use query based on Workflow Job ID ?

I want to find out what are the users been processed in the custom task.
