I'm trying to create a column in a query to look across other columns in a query and tell me the earliest date. It's a qualifications expiry report. There are 5 qualifications hard coded into the query. The expiry date is a calculated key figure. I've tried using MIN ( , ) but this only works for two qualifications and if the date is blank, it's treats this the a minimum date. I've also tried using an IF statement and nesting them but this returns numbers rather than a date, even if I use 'Process Value as Date'. Essentially I need the column so that I can sort on it as the report will generate about 6000 rows.
Example Date 1 01.05.2005
Date 2 01.06.2005
Date 3 01.07.2005
I would like to see 01.05.2005 in a new cell called date 4
Any help would be much appreciated.
