Hello,

im developing a custom ssrs report, i need it to print data based on selected sales line itemid. so lets say i have a sales order with 3 sales lines, and i select the 1st row, it should get me the data based on the first row's itemid ,knowing that each row has a different itemID. i developed the Contract, controller and DP classes. after debugging the code, i found that in the processReportParameters() method in the controller class, the buffer "contract" is always null, which is related to the contract class. when i try to print the report, its giving always error that "Something went wrong while generating the report. Please try again."

i would appreciate your help in my issue.

Thanks

[DataContractAttribute]
class ContractClasz
{
    private ItemId itemId;


    [DataMemberAttribute('ItemId')]
    public ItemId parmItemId(ItemId _itemId = itemId)
    {
        itemId = _itemId;
        return itemId;
    }

}

public class SalesControllerClasz extends SrsReportRunController
{
    protected void PrePromptModifyContract()
    {
        ContractClasz contract = this.parmReportContract().parmRdpContract();
        this.processReportParameters(contract);

    }
    void processReportParameters(ContractClasz _contract)
    {
        ContractClasz contract;
        SalesTable SalesTable;
        SalesLine SalesLine;

        if(this.parmArgs().record().TableId == tableNum(SalesLine))
        {
            if(this.parmArgs() && this.parmArgs().record())
            {
                contract = this.parmReportContract().parmRdpContract() as ContractClasz ;
                SalesLine = this.parmArgs().record();
            }
            _contract.parmItemId(SalesLine.ItemId);
          
        }
    }
    public static void main(Args _args)
    {
        SalesControllerClasz controller = new SalesControllerClasz();
        controller.parmArgs(_args);
        controller.parmReportName(ssrsReportStr(ReportTTT, Design));
        controller.startOperation();
    }

}

Hi,

Contract Class Issue: Ensure your contract class has the correct DataMember attribute and is correctly initialized in the controller.
Passing Parameters: The controller should correctly pass the selected SalesLine’s ItemId to the contract.
processReportParameters() Issue: If the contract is null, check if it's properly assigned using parmRdpContract().
DP Class Filtering: Ensure your DP class retrieves the contract and filters data based on ItemId.
Menu Item Data Source: If your report is tied to a specific table, the menu item in the data source should point to the correct table.(check the form etc)
Debugging: Add breakpoints in processReportParameters() and verify args.record() to confirm you're getting the selected SalesLine.

Thank you!

Hi,

When you debug, does it reach this line?

contract = this.parmReportContract().parmRdpContract() as ContractClasz;

You need to use the debugger to find the actual exception.

Your code in processReportParameters() is weird:

Whether contract variable is null or not isn't important, because you never use it for anything.

You're using the value of salesLine.ItemId even if you didn't populate salesLine variable.

You're using the value of this.parmArgs().record() before checking whether you have any Args at all. You need to change the order of the conditions.

You've declared salesTable variable, but you never use it.

Hello,

Try modifying this part of the code as follows :

public class SalesControllerClasz extends SrsReportRunController
{
protected void PrePromptModifyContract()
{
ContractClasz contract = this.parmReportContract().parmRdpContract() as ContractClasz;

if (!contract)
{
contract = new ContractClasz();
this.parmReportContract().parmRdpContract(contract);
}

this.processReportParameters(contract);
}

void processReportParameters(ContractClasz _contract)
{
SalesLine salesLine;

if (this.parmArgs() && this.parmArgs().record().TableId == tableNum(SalesLine))
{
salesLine = this.parmArgs().record() as SalesLine;

if (salesLine)
{
_contract.parmItemId(salesLine.ItemId);

// Ensure the contract is updated in the report contract
this.parmReportContract().parmRdpContract(_contract);
}
}
}

public static void main(Args _args)
{
SalesControllerClasz controller = new SalesControllerClasz();
controller.parmArgs(_args);
controller.parmReportName(ssrsReportStr(ReportTTT, Design));
controller.startOperation();
}
}
