We all know that data validation is a very useful feature in Excel. You can use data validation to create a drop-down list in a cell and limit the values user can enter. But, do you know that you can use data validation in a multitude of ways to prevent users from entering wrong data?
Here is a practical application: Prevent users from entering duplicate values in a range of cells.
For eg. you are making an invoice. Wouldn’t it be cool if Excel prompted you when you enter a duplicate line item so that increase the item quantity instead of repeating it.
Here is a 3 step tutorial to do just that.
Step 1: Identify the range of cells where you want only unique values to be entered
This is simple. All you have to do is find the range where you want to control the user input. Lets say the range is B4:B11
Step 2: Set up Data Validation to prevent duplicate entries
Select the range (B4:B11) and go to data validation (Excel 2007: Data Ribbon > Data Validation, or press ALT+AVV)
Now, specify the validation type as “Custom”, this will allow us to use formulas to check for valid data. In our case, we need check if a particular entry is duplicated in the range B4:B11. This can be easily done using COUNTIF formula [learn COUNTIF Formula in plain English].
Go to the formula field and type the countif formula like this: =COUNTIF($B$4:$B$11,B4)<=1
Also, you can set up the “Error Alert” so that you can show a custom message when a duplicate value is typed, like “You have already added that product” message.

Once you set up error message, it will show up like this:

Step 3: Sit back and Relax
The third step is all too familiar. Now that you have prevented duplicate entries in your spreadsheets you can sit back and relax. May be read a few more spreadcheats.

Good Work, Yogesh & Chandoo! Thanks.
Hi everybody,
first sorry I am late to say something about this topic;actually I was waiting last part
second I am not accountant I am an Engineer
third """"Very Important""" the idea is not about Loss but I am sure it is profit
Based on third it shows:

2- How to use pivot TABLES
3- How to collect and arrange DATA
4- How to make reports
Many Thanks
Hi Yogesh and Chandoo,
Thank you for sharing your knowledge!
You guys are great!
thanks chandoo and yogesh, thanks for you lessons, are great!....i have a idea for a budget. I try to do it..... thanks for all
Thanks a lot for sharing the most powerful tool worldwide "knowledge"
Warm greetings from Peru
Hi -
This is a really great article because it's a simple and common thing you'd want to do with a pivot table but not at all obvious how to do it! So - muchas gracias to Chandoo and Yogesh!
One thing - I couldn't get past the group error in the sample file. I would click on ungroup but it didn't seem to have any effect. I'd appreciate it if anybody has any pointers here.

Hi Chandoo
I am also having the group error. Can't seem to ungroup? Appreciate if you explain further on the steps required in order to get to calculated items.
Many thanks and keep up the great work.
Cheers

Hi Chandoo,
I'm struggling resolving the problem depicted below:
I have a set of data, with (among others) a "Region" field (can be APJ, EMEA, or AMS), and a "Country" field.
Unfortunately, I need to group data by the following 4 Regions: APeJ, Japan, EMEA and AMS.
I first tried to make a pivot with Region and Country in the rows (or columns), and then group Country data as per the above.
Alas, as soon as I have a new Country that appear in my data set, my groupings are broken, and I have to redo the job of ungrouping, grouping etc.
I thought I could try to use calculated item, by adding first a new column to my dataset concatenating Region_Country, and create an "APeJ" calculated item that would sum all the "APJ_*" and substract the "APJ_Japan", but again, no clue, as I can't find a way to use any wild card in those formulas.
Given that I already found extremely helpful tips and tricks in your site that helped me manage that bunch of data, I'm pretty sure you'll have a bright idea on how I can solve that one!
Thanks in advance for your lights!
Hi Catherine...
In such cases, I advice using an additional column in the data itself. You can set-up a grouping table else where with country in first column, region in second column. And then in the data, you can add an extra column and use VLOOKUP to fetch the region based on the country.
Then feed this entire data (with extra column) to pivot table and use the extra column to group the data.
Hi Chandoo,
Thank you for your prompt answer.
I finally came to the same conclusion - after a rest 🙂 . I was probably too tired Friday evening (it was rather late), having spent hours in manipulating all my surveys data so as to pull rolling averages, make nice graphs and so on, and was trying to find a complex solution when there was a simple one.
Thanks again,
Catherine
Hey,
Great post!
I for example have different database structure with the following fields :
Date, Expense, Income, Sum (Income - Expense), Category (Sales, Cost of Goods and etc).
Creating a P&L report for the whole year works great. Including gross margin % and etc.
Though, creating P&L report by QTR/Month is becoming impossible since i get the following error : “This PivotTable report field is grouped. You cannot add calculated item to grouped filed.”
Is there a solution for this kind of problem?
Like Adam and Juanito, I also cannot ungroup.
Would appreciate it if you can add a few more lines and a screenshot or two on where to put the mouse cursor to ungroup.
Hi, I have figured out the ungrouping problem. One of the earlier steps was to group by month, if you pull the month back down to the column then right click and then select ungroup, then pull the month back up so you end up with just data source and budget/actual as the headings, then you can continue on.
To solve the ungroup problem, my method is:
Copy the "data" sheet to a whole new Excel workbook
and directly work on Part 6.
And since it is a fresh copy, Excel don't show me the "can't ungroup" problem. Hope this help.
Thank you Yogesh for this wonderful tutorial.

Just when i thought pivots were awesome i learn about inserting the calculated fields and that makes them more awesome. chandoo where have you been all my life.
Hello - your P&L pivot version has really impressed my boss and would like to use it. I have applied it for a actual vs budget vs forecast model I have created. One problem. In your variance above the operating profit percent % variance shows 33.8% but I want it to show (0.01) point or the true diff from prior budget.
I know I can add calculation to the side but boss would like to see it in pivot table.
Please help
Thanks
I have a further query which may solve my above dilemma. Is it possible to add a column that calculates percent increase. So in the example above a new column would be added to show variance %.
Any help would be appreciated.
Thanks
