Depending on what your first day of the week is, you would need to have a WDAYS value of either 5 or 6. The DAYS field would be L08,L09,L10,L11,L12,L13,L14. Since you are using L values in the DAYS you will need a value in DCAL. We have a calendar named ALLDAYS in which every day is a work day and we utilize this. Your AND/OR value would be A.
To sum up
DAYS : L08,L09,L10,L11,L12,L13,L14
WDAYS: the site value for Friday
