Okay, so if I want it, I'll have to make it. Hopefully this won't be too painful. :) Any thoughts on where to start? The way I see it, I have to do this:* create a table for holidays which can include weekends, identified by the day of the week or a calendar date* add two booleans to the SLA table, one to ignore weekends, the other to ignore holidays* add two checkboxes to the new/edit SLA screens to control the previous item* Add logic to wherever an SLA returns how much time it has left that automatically looks for any holidays/weekends (if the SLA is set to do so) and adds that time to what it returnsI don't know if my boss will want me to spend all that time on this, but if he does, where would I begin? As I said, modifying the database won't be a problem, it's the OST code that is a bit daunting. Thanks.
