User-defined Function Basics

User-defined functions, like the built-in functions, are not associated with a specific report definition. Therefore, you must use parameters instead of direct table and field references in the UDF expression. Parameters pass actual values from the database or user-defined fields into the UDF expression. This indirection allows you to use the UDF with multiple reports.

When you create a UDF, Report Builder saves it in a file called prorb.udf. By default, Report Builder attempts to create prorb.udf in the Report Builder program directory. For information on how to place prorb.udf in a different location, see "Report Builder Administration."
