To call Stored Procedure from crystal report,
Set data source of report to Stored Procedure (DataBase Expert Wizard). That procedure must met thses requirement
1- You must create a package that defines the REF CURSOR (type of field that will be retrieved).
2- The procedure must have a parameter that is a REF CURSOR type. This is because CR uses this parameter to access and define the result set that the stored procedure returns.
3- The REF CURSOR parameter must be defined as IN OUT (read/write mode).
4- Parameters can only be input (IN) parameters. CR is not designed to work with OUT parameters.
5- The REF CURSOR variable must be opened and assigned its query within the procedure.
6- The stored procedure can only return one record set. The structure of this record set must not change, based on parameters.
7- The stored procedure cannot call another stored procedure.
