Carry Over Totals

[#1]

Hello All,

I have a situation where I need to carry over the totals from the previous month to the latest month.

let's say...

	Month	March 2013	March 2013
Type	Item Type	A	B	Total
Beginning		200	0	200
Sales		400	500	900
Loss		800	100	900
Total		1400	600	2000

So the contents are Quantity.. so the Total 2000 should carry over to the next month (April 2013)

	Month	April 2013
Type	Item Type	A	B	Total
	Beginning	1400	600	2000
	Sales	500	700	1200
	Loss	850	150	1000
	Total	2750	1450	4200

Total will also carry over the next month and so on..

The data I have where sales and loss, items types are all coming from the database, while my beginning balance only comes from

an excel file that I need to merge to the database.

Are there any way I can achive this?

Thank you,

Donna

You can add a field to your calendar script as num(Month(Month)) as Month_Num and replace Month in the table expressions with Month_Num.
Modify the definitions for variables as follows:
1. vCurrentMonth
Definition: =num(Month)
2. vPreviousMonth
Definition: =if(num(Month)=1,12,num(Month)-1)
Use something like this expression for Current month
=num(avg({<Month_Num={$(vCurrentMonth)}>}MeanTotal)/100,'##%')
Use something like this expression for Previous Month
=num(avg({<Month_Num={$(vPreviousMonth)}>}MeanTotal)/100,'##%')
