Descending number sequence with Dates (Months) as the heading
Assuming my heading is the time: Jan 19, Feb 19 to Dec. 20. This is due to a parameter set. and the range changes based on the parameter to be set.
My line item will be Date in number. this will make Jan 20  Dec 20 to 1, 2, 3 and so on. I have successfully sequenced Jan 20  Dec 20.
However Jan 19 to Dec 19 will have to be sequenced as 12, 11, 10 and so one. Making Dec 19 the 1 in the sequence.
How can i possibly pull this off using a number format?
Thanks,
Elaine

Absolutely!
Here's my time selection module and formulas:
The Year difference formula is very important:
ROUND((START(Launch Year)  START(Start Year)) / 365) * 12
And here's the formula for the Number line item in a module dimensioned only by time
IF ITEM(Time) < Time selection.Launch Year THEN IF ITEM(Time) = Time selection.Start Year THEN Time selection.Year difference * 1 ELSE PREVIOUS(Number) + 1 ELSE IF ITEM(Time) = Time selection.Launch Year THEN 1 ELSE PREVIOUS(Number) + 1
Result:
Let me know if that works

Hi Elaine,
Assuming your line item is called Number, try this formula in the line item
IF ITEM(Time) = Time.'Jan 19' THEN 12 ELSE PREVIOUS(Number) + 1
Let me know if it works

It looks good except that u hardcoded "12" in the formula. Is there a way to not hard code it?
Assuming the parameters state that:
Start year: FY18
Launch year: FY20
That is where the users set the parameters. So the start month of Start year and Launch year is January. From that given info, how can i make the sequence without hardcording the distance between Jan 18 (being the 24) and Jan 20 (being the +1). No "0" in between the +1 and the 1 by the way.
Thanks again,
Elaine

Here is solution that hopefully works for you, I broke it up into 3 line items:
Elaine: IF ITEM(Time) = IF ITEM(Time) = SYS Global.Elaine Date THEN 1 ELSE IF NEXT(Elaine) = 1 THEN 1 ELSE IF ITEM(Time) < SYS Global.Elaine Date THEN NEXT(Elaine)  1 ELSE 0
Next Elaine: IF ITEM(Time) > SYS Global.Elaine Date THEN PREVIOUS(Elaine) + 1 ELSE 0
Final Elaine: Elaine + Next Elaine
Hope this helps,
Rob
