I think custom sort is the only proper option.
As far as I am aware you can type manual values as well (even if they don’t exist in the database)
Or you could create a formula that concatenates number of month and year i.e. 01-2008 / 02-2008 / 01-2009
After this is done you can sort by the this column and make it “invisible”.
Hi Sachin,
Rim is right. But just one change in the suggestion, instead of arranging the field as MM-YYYY try using YYYY-MM. The reason being if you use it exactly as Rim suggested, the 01-2009 will be before 12-2008 in case it gets sorted alphabetically. If you use a Date type variable then it should work fine. But otherwise, just use the YYYY-MM format and you dont have to worry about whether it uses character sort or date sort.
Also I’m sure you’re aware that if you are using WebI then it will not be possible for you to hide the column directly. So you will need to minimize the column width and match the font color with the background in order to make it invisible.
