Any ideas how I can work back from the year and week number to get a date (any date in the week will do)

Dan

Dear Dan,

Monday.date.in.a.week=week.to.num (http://www.baanboard.com/programmers_manual_baanerp_help_functions_date_time_zones_week_to_num)(weekno,yearno,2)
Provided that Sunday is the first day of the week

Rgds,
Paul
