What LB is starting to ask for is more technical information, such as:
Crystal version
Database used
Example data
Expected output
Using text descriptions to provide a spec will likely net more questions, if not confusion, so simplify everyone's life and demonstrate the environment and requirement.
To eliminate weeknds (and if you need to eliminate Holidays as well you should so state) from data returned from the database try Report->Edit Selection Formula->Record:
day({table.date}) in [1 to 5]
and
{table.date} >= currentdate+1
This is just a wild guess of course, you've given no indication as to where this might be used, nor for what prupose, amongst the other unknowns.
Hope it helps though.
