Crystal Reports is a popular tool used for creating dynamic and interactive reports. One common need that many users have is to use calculated values from the footer section in their reports. While this may seem complicated at first, it is actually quite simple to accomplish.
In Crystal Reports, the footer section is typically used to display summary information for the entire report, such as totals or averages. However, sometimes users may want to use these calculated values in other parts of the report, such as in a formula or in a text box. This can be easily achieved by using shared variables in Crystal Reports.
How to use calculated value from footer in Crystal Report?
To use a calculated value from the footer in Crystal Reports, you will need to create a shared variable. Here’s how you can do it:
1. In the footer section of your report, right-click on the field that contains the calculated value you want to use.
2. Select “Insert” and then choose “Summary.”
3. In the “Insert Summary” dialog box, select the summary type (e.g., sum, average, count) and the field you want to summarize.
4. Click “Insert” to add the summary field to the footer section.
5. Now, right-click on the summary field in the footer and select “Edit Summary.”
6. In the “Edit Summary” dialog box, go to the “Show” tab and make sure that “Calculate this summary” is checked.
7. Next, click on the “Shared” tab and give your shared variable a name (e.g., {@TotalSales}).
8. Click “OK” to save the shared variable.
9. Now, you can use this shared variable {@TotalSales} in any formula or text box in your report.
FAQs
1. Can I use multiple shared variables in a Crystal Report?
Yes, you can create multiple shared variables in a Crystal Report and use them as needed in your formulas and text boxes.
2. Can I use a shared variable in a conditional formula?
Yes, you can use a shared variable in a conditional formula to perform calculations based on certain conditions.
3. Can shared variables be used across different sections of a report?
Yes, shared variables can be used across different sections of a Crystal Report, allowing you to pass calculated values between sections.
4. Is there a limit to the number of shared variables that can be created in a Crystal Report?
There is no specific limit to the number of shared variables that can be created in a Crystal Report, but it is recommended to use them judiciously for better performance.
5. Can shared variables be reset or cleared during the report runtime?
Yes, shared variables can be reset or cleared during the report runtime by using formulas to assign new values or nullify existing values.
6. Are shared variables stored globally or locally within a report?
Shared variables are stored globally within a report, allowing them to be accessed and modified from different sections of the report.
7. Can shared variables be used to perform complex calculations in Crystal Reports?
Yes, shared variables can be used to perform complex calculations by storing intermediate results and using them in subsequent calculations.
8. Can shared variables be used in cross-tab reports in Crystal Reports?
Yes, shared variables can be used in cross-tab reports to calculate totals, averages, or other summary values for the data displayed in the cross-tab.
9. Can shared variables be used to pass values between subreports in Crystal Reports?
Yes, shared variables can be used to pass values between subreports in Crystal Reports, allowing you to share calculated values across different subreports.
10. Can shared variables be used to display dynamic text in a text object?
Yes, shared variables can be used to dynamically display text in a text object based on calculated values or conditions in the report.
11. Can shared variables be used in charts and graphs in Crystal Reports?
Yes, shared variables can be used in charts and graphs to display calculated values as data labels or tooltips for better visualization of the data.
12. Can shared variables be used to perform conditional formatting in Crystal Reports?
Yes, shared variables can be used to perform conditional formatting by evaluating certain conditions and changing the appearance of the report objects based on those conditions.
