In Crystal report 2011 I have main report rptMain and subreport SumMain .
They are linked with a field Supplier ID. In main report I have parameter Month Of Report I want to pass this parameter value to sub report.
When I go to sub report link form I see that I have supplier ID field as field to link to I am adding month of report too on the right side bellow Supplier Id and everything looks ok.
In sub report when I create formula and in that formula use parameter ?Month of Report I got error “This field name is not known” and parameter field is highlighted.
