Error when processing Crystal Report “Operation illegal on linked parameter”

I was recently caught up with this Error “Operation illegal on linked parameter” when working with the Crystal Reports and solution seems to be pretty simple too .

When you run a Crystal Report which inturn contains the SubReports , the Crystal Report issues the following error:

Operation illegal on linked parameter

The Error Message is preceded by the ReportName that is processed.

The error Message occurs when a parameter field in a subreport is used to link the subreport to the main report called as “linked parameter” .

When a linked parameter is present , its value is filled automatically at run-time from the parent report’s value.

When the Values are explicitly passed by the program / Application, the Error Message Appears ..

To solve the issue , do not specify the values for the linked parameter as these values are not meant to be set directly ….
