preventive order in SAP

Hi dudes,

in preventive maintenance, I have created suitable time-based package, task list and then planned it in IP42.

I want this maintenance tasks tobe done on non-working days weekly so I set start cycle on a non-working day and the period time is & days.

when i run IP10 everything is ok and all call dates are on weekend(for example 26.05.2010), but when it gets to planed date and the order creates the date is the next day (27.05.2010). I deleted factory calendar from the work center and the scheduling indicator in maintenace strategy (IP11) is* time* (not ) time-factory calnd .

what can I do? is it standard of SAP that doesn't let PM orders being created on non-working days?

thank you in advance
