50% of workforce on non-work days

Thank You Bill,
Can You be a little bit more detailed. The resource curve based on duration percentage, so how can I hit the non-work days with the half workforce for hundreds of activities with different start date?

dear katalin,
to make it 50% resource in non working days as u said absolutely cannot be done unless at first setup the file u select planning unit in hrs...the other way, u can define every activities that working in non working days then u have to deduct 50% using global change or manual calculation. Its little bit tedious...to select one by one from the budget cost.
regards
