Identifying relevant data based on multiple values

[kun77]

I’m trying to figure out the following for my research. If anyone can please help.

A	B	C	D	E	F
Comp	FY	Prod	Rev	Total_rev	Target
ABC	2009	soap	100	1000	1000
ABC	2009	shampoo	800	1000	1000
ABC	2010	toothpaste	500	200	alpha*total_rev of FY 2009 of ABC
ABC	2010	soap	1100	2000	alpha*total_rev of FY 2009 of ABC
ABC	2011	buiscuits	1200	3000	alpha*total_rev of FY 2010 of ABC
XYZ	2009	Desktop	150	5000	5000
XYZ	2010	Laptop	100	7000	alpha*total_rev of FY 2009 of XYZ
XYZ	2010	Desktop	50	6000	alpha*total_rev of FY 2009 of XYZ
XYZ	2011	Mobile	200	7000	alpha*total_rev of FY 2010 of XYZ

The table is read as:
Col A: Company name
Col B: Financial Year
Col C: Products sold
Col D: Revenue for that product
Col E: Total revenue of the company in that financial year
Col F: Target


Target is being calculated as following:

If FY <= 2009 (base year) or lower, target = total revenue of FY 2009.
If FY > 2009, target = alpha * total rev of (FY -1) for that company. Hence, target for 2011 = alpha * total rev of 2010 for that company.

Any help would be highly appreciated.

Thanks.

Array Formulae are a little different from ordinary formulae in that they MUST be confirmed in the FIRST CELL ONLY by pressing CTRL+SHIFT+ENTER to activate the array, not just ENTER. After that, the array can be dragged down as normal, to cover the desired range.

You will know the array is active when you see curly brackets { } - or "curly braces" for those of you in the USA, or "flower brackets" for those of you in India - appear around the outside of your formula. If you do not use CTRL+SHIFT+ENTER you will (almost always) get an error message or an incorrect answer. Press F2 on that cell and try again.

Don't type the curly brackets yourself - it won't work...

Glenn - did you forget the formula?

Bad hair day!! I meant to use this canned reply:

Will you please attach a SMALL sample Excel workbook (10-20 rows of data is usually enough)? However, please give us an indication of the approximate number of rows of data you want the solution to work with (100, 1000, 100,000 or whatever). Please don't attach a picture of an Excel sheet (no-one will want to re-type all your stuff before starting).

1. It does NOT have to be your real sheet - mock up a SAMPLE if you need to. But not 1000's of rows!!! It makes manual checking so tedious. Whatever you do... make sure that all confidential information is removed first!!

2. Make sure that your sample data are truly REPRESENTATIVE of your real data. The use of unrepresentative data is very frustrating and can lead to long delays in reaching a solution.

3. Make sure that your desired solution is also shown (mock up the results manually).

4. Try to avoid using merged cells. They cause lots of problems!

Unfortunately the attachment icon doesn't work at the moment. So, to attach an Excel file you have to do the following: Just before posting, scroll down to Go Advanced and then scroll down to Manage Attachments. Now follow the instructions at the top of that screen.

Clearly the OP is having a bad hair day, too... as the description of his request has now disappearred...

Been there, done that very recently.
