Using Amper Variables as Parameter Values

When a parameterized report is scheduled, you can set the value of a parameter to a variable, rather than a literal value. This ability reduces the need for a schedule to be updated before it is run. For example, instead of editing a schedule daily in order to display up-to-date information, a report can be scheduled to always display the date of the day that it is running. This is done by setting the value of the parameter as &YYMD. In the Task Parameters dialog box, there is a check box labeled The value contains a system variable, as shown in the following image.

The Task Parameters dialog box. The the value contains a system variable check box is selected

This check box is cleared by default. When this check box is selected, a string beginning with the ampersand character is processed as a variable. When this check box is cleared, the ampersand character is then processed as a literal value. This feature works with both system variables, and global variables that have been set in the Reporting Server global profile edasprof.prf.

Example: Using the &YYMD Variable as a Parameter Value

The following syntax is a sample report procedure (FEX) that contains date parameter values that can be used with the &YYMD Variable. 

-*COMPONENT=Define_wf_retail
DEFINE FILE retail_samples/wf_retail
Sale_Date/YYMD='&Sale_Date.Sale Date: Use &|YYMD in Schedules.' ;
 Last_Year/YYMD=Sale_Date - 365 ;
 Two_Years_Ago/YYMD=Last_Year - 365 ;
 Quantity/D12.2=IF WF_RETAIL.WF_RETAIL_TIME_SALES.TIME_DATE EQ Sale_Date THEN WF_RETAIL.WF_RETAIL_SALES.QUANTITY_SOLD ELSE 0 ;
 Prior_Year/D12.2=IF WF_RETAIL.WF_RETAIL_TIME_SALES.TIME_DATE EQ Last_Year THEN WF_RETAIL.WF_RETAIL_SALES.QUANTITY_SOLD ELSE 0 ;
 Two_Years_Past/D12.2=IF WF_RETAIL.WF_RETAIL_TIME_SALES.TIME_DATE EQ Two_Years_Ago THEN WF_RETAIL.WF_RETAIL_SALES.QUANTITY_SOLD ELSE 0 ;
