# Crystal Reports - How to calculate the difference in Cross tab and few more calculation

Hello,

Am using crystal report V12.3. This is a continuation of my previous post (Crystal Reports need to find the max & minimum value for dynamic input). My initial requirement was satisfied with the Cross-tab concept but to further drill down to the requirement i need to find the difference between the values obtained in the Cross-tab concept. I have attached the image showing (sample) the calculation required.

And also How to save or get the values (output) derived from the cross tab concept? so that i can find the difference and use those value in my further calculation.query.jpg

And also Please tell let me know how to remove those default Totals (both Row and column) from the display of Cross-tab section, as I require only difference.

Hi Kayalvizhi,

Are 'Minimum Qty' and 'Maximum Qty' two separate summary fields inserted in the crosstab?

To suppress the 'Total' fields, right-click the 'Total' field on the Row > Row Grand Totals > Suppress Grand Totals.

Repeat the same for the Column Totals by selecting 'Column Grand Totals' > Suppress Grand Totals.

Hi Abhilash,

'Minimum Qty' and 'Maximum Qty' are same field showing the Maximum & Minimum value of that particular field.

Yeah I do did that supress but still displaying the blank space in the place of "Total".

How to save or get the values (output) derived from the cross tab concept? i.e., I want to use the Maximum & Minimum value derived from this Cross-tab for other calculation. Is that possible?

Did you suppress the 'Total' text field or suppress the Totals using the method I posted above? What I posted above doesn't leave behind any empty space.

Here's what you need to do for calculating the Difference:

1. Right-click the Maximum column (which I believe is the last column) > Calculated Member > Choose the option 'Select "Maximum' as first value.

2. Right-click the Minimum column > Calculated Member > Choose 'Difference of Maximum and Minimum'.

3. A new calculated column called 'Difference' should be inserted. Right-click the header cell of this column > Select Calculated Member > Edit Insertion Formula > Modify the code to:

GetColumnGroupIndexOf(CurrentColumnIndex) = 0

This will move the Difference column to the end of the crosstab.

Thank you. I will try this "Difference" and let you know the result.

Is there way to get (assign it to a variable or formula field) the Maximum & Minimum value derived from this Cross-tab for other calculation?

Hi Abhilash,

I have attached the output of my Crosstab, Cross-tab expert and Crystal Report design.

1. Right-click the Maximum column (which I believe is the last column) > Calculated Member > Choose the option 'Select "Maximum' as first value. - am not getting "Calculated Member option" and Maximum & Minimum are shown as Column. (Sorry to mislead by my first attachment, as that was my required output but I couldn't bring it like that). Please let me know how to find the difference between maximum and minimum with the attached design.

And Is there way to save(assign it to a variable or formula field) the Maximum & Minimum value derived from this Cross-tab for other calculation? i.e., i want to use this Maximum and Minimum value derived outside the Cross tab.

The steps I mentioned above will not work with the design you have.

Here's what you need to do:

1. Right-click the Minimum value under the 'Green' column > Select Embedded Summary > Insert Embedded Summary.

2. You should cells labeled 'Edit this formula'.

3. Right-click this cell > Embedded Summary > Edit Calculation Formula > Use this code:

GridValueAt(CurrentRowIndex, CurrentColumnIndex, 1) - GridValueAt(CurrentRowIndex, CurrentColumnIndex, 0)

That's great Abhilash. Difference Calculation worked perfectly but am getting a minus (-) symbol in the front. Please find the attached image.

And also i want to sum the Difference of each Column & Row to derive another value. For example in the attached, i want to Sum the Difference value under "green" column and also i need to Sum the Difference value under "Apple" row. Is that possible?

Is there way to save the value from Cross-tab? (either Embedded Summary or the Max Min value)24feb-2.jpg

Sorry, the formula should be:

GridValueAt(CurrentRowIndex, CurrentColumnIndex, 0) - GridValueAt(CurrentRowIndex, CurrentColumnIndex, 1)

Also, Where would you like to display the addition of Row and Column 'Difference' columns? Outside the crosstab or within the crosstab as a new Row and Column?

Thank you. Latest formula worked !!!

I would like to display the addition of Row and Column 'Difference' columns within the crosstab as a new Row and Column and also i need to store these values Outside the crosstab because here am trying to build a complex report with many calculations or manipulation. So I need these addition of Row and Column 'Difference' columns outside the cross tab as well (i.e., how to save or store the values calculated from Cross-tab concept?).
