Calculate difference between summarized data column and static table

[MichaelHearst13]

Hi all,

I have actual sales data synched and summarized (date hierarchy -- month) from my SQL server (let's call this Ledger), and a static table that I created with monthly sales targets (let's call this Sales Projections). I want to calculate Ledger - Sales Projections.

I've tried to calculate the the results of numers solutions for taking the difference between columns without any luck.

Does anyone have any ideas on how I may calculate the difference?

Thanks in advance!

Can you share how those tables are connected and what the columns in those tableS?

table 1)	Ledger		table 2)	Calendar/Date Table	table 3)	Sales Projection
	trans_date	Sales		Date	MonthNameLong		Month	Sls/Day	Sales (forecasted)
	1/1/2017	500		1/1/2017	January		January	682	15000
	…	..		…	..		February	650	13000
	..	..		..	..		March	….	…
	2/1/2017	480		2/1/2017	February

Based on what i see, you need to have date in sales projection instead of month and link that date with calendare date table, also ledger will have relation on trans date to date column in calendar table and it should be straight forward from there. let me know if you already tried this.

and you will get something like this and can be further enhanced as needed

Sure --

Below is a rough example:

Ledger has hundreds of thousands of lines, connected (green) to a calendar table by each date

Calendar table connects (pink) to a summary Sales Projection table.
