OfficeWriter Enterprise Edition allows you to create custom formulas. The formulas can be based on query results, report parameters, or they may access a set of global variables that Reporting Services contains.


Reporting Services Global Variables
Reporting Services contains global variables that you can access if you have OfficeWriter Enterprise Edition. To access the global variables:
 On the OfficeWriter toolbar, click Formulas and select Add Formula.
 In the Insert Formula dialog, click the + next to Globals to open the list of Reporting Services global variables.
You will see six global variables:
Execution Time
The report's execution time
Report Server URL
The URL of the server running the report
Report Folder
The folder on the Report Server containing the report
Report Name
The Name of the report
User ID
The ID of the user logged on
Language
The report language
 Select Execution Time from the list.
 Click Insert and Ok.
 Click Formulas and select Add Formula.
 Expand the Globals list.
 Select Report Server URL from the list.
 Click Insert and Ok.
 Repeat the steps above until you have added all six global variables. When you select Formulas, you should see:
Parameters in Reporting Services Formulas
You can also use this approach to build formulas that use the parameter values. These formulas can be inserted into the report to display the parameter values selected when running the report.
 Select Formulas > Add Formula
 Expand the Parameters section
 Select a parameter and click the Insert button
 Click OK.
Building Formulas from DataSets
This section will cover how to create a formula using data from a data set. This particular example will use the SUM function:

 Click the + to expand the Formulas list.
 Scroll down, select SUM, and click insert.
 Click the + to expand the DataSets list.
 Find your query and click its + to open it.
 In the Expression list on the right, highlight everything inside the SUM parentheses, as shown.
 Click SalesAmount and Insert. Your formula should now look like this:
 Click Ok to return to your worksheet.
Inserting Formulas into an Excel Report
To insert a formula into a cell in an Excel report:
 Place your cursor in the desired cell
 Go to Formulas in the OfficeWriter Designer toolbar
 Under the Insert Formula section, select the formula to insert into cell
Below is an example of a template that has formulas for all the global variables and a formula made from a data set:
Here is what that example template looks like when it's been populated with data:
