The @Variable function is used in the WHERE clause to call the value assigned to one of the following variable types:
SAP BusinessObjects system variables
Report variables
Language (Locale) variables
Operating system variables
Insert the @Variable on the operand side of the condition in the WHERE clause for an object. The query retrieves the value for the variable.
Note
The @Variable is a monovalue function and cannot be used with the IN or INLIST operators.
When the same @Variable function is executed several times in a query, the prompt only appears once.
You can use the @Variable function with the @Prompt function in the same query when the @Prompt function is monovalue
