Hi,
I would be grateful if someone could point me in the right direction - as I'm clearly being daft!
I have a report that summaries the SalesValue measure (which is an aggregate function in the universe)
Week 1 £1000
Week 2 £1500
Week 3 £900
I have created a variable TOTAL SALES (sum(salesvalue)) which successfully displays £3400.
I have created a variable for average (Total Sales /3) which displays £1133.33.
What is the best way to create a variable for each week to show the difference between the average (£1133) and the sales for the week i.e Week 1 = +133, week 2=+367, week 3 =-233.
Whenever I create this variable (SalesValue-Average) and put it next to week it doesn't calculate based in the total sales (£3400)
I'm sorry if this is one of those easy simple things but I am new to WEBI and I'm struggling.
Many thanks in advance.
Jude
