What you do first when u open the View before that Just Update the paramenter field,so that u can pass your field, and can get the value.if you made any changes in the procedure you need to update the fields in the crystal report.

I have researched a lot for the issue and later found out that it is the problem with the runtime /developer versions of SAP crystal report. Probably the report might be created in one version (for eg: 13.0.6) and right now you may be testing with a newer version (a new runtime/ developer version 13.0.12). In order to resolve the issue, remove all versions of SAP crystal report from your machine, delete the SAP folder from program files, restart and install the old version of CR and test.

Thank you! All the best!
