1538385 - Error: "Exception in formula '{@Formula name}' at 'StoreStringVar': UFL 'u25store.dll' that implements this function is missing." when viewing report in Crystal Reports

Symptom

  • Error in formula when refreshing report in Crystal Reports.
  • After migrating reports developed in older version of Crystal Reports, an error message is displayed as: 
          
    "Exception in formula '{@Formula name}' at 'StoreStringVar': UFL 'u25store.dll' that implements this function is missing."

Environment

  • SAP Crystal Reports 2008
  • SAP Crystal Reports 2011
  • SAP Crystal Reports 2013
  • SAP Crystal Reports 2016

Reproducing the Issue

  1. Create a report in Crystal Reports 8.5 with a formula with name @myFormula
      
  2. Write the following code in formula @myFormula: 
       
        StoreStringVar('var_name','var_value');
      
  3. Migrate the report to a newer version of Crystal Reports.
       
  4. It will then generate the error.

Cause

  • The functions StoreStringVar, StoreNumberVar are implemented in the User Function Library (UFL) u25store.dll, and it is not distributed with Crystal Reports.
      
  • A User Function Library (UFL) is a way to add additional functions in Crystal Reports. This UFL was created for Crystal Reports 5 and 6 to be able to share data between subreport and main report. ( Subreport were added in Crystal Reports 5 ) 
       
  • In Crystal Reports 7, shared variable was added to the core product to be able to share values between the main report and the subreport, therefore no external UFL like: u25store.dll is required to share values with a subreport or main report.

Resolution

  • Uses Shared Variable to share values between the main report and subreport.
        
  • For example, in the formula @test, replace the code from: 

        StoreStringVar('var_name','var_value')

    To 

        Shared Stringvar var_name := "var_value";
