How to add a validate method in AX 2012 SSRS report

Following are the two steps required if you want to add a validation on SSRS report dialog form or want to make a specific field mandatory for a report:


1. Implement the contract class by SysOperationValidatable

public class ProjTransReportContract implements SysOperationValidatable

2. Add the validate method

public boolean validate()
{
    boolean             isValid = true;
    ;

    if (this.parmFiscalYear() == '')
    {
        // Fiscal year was not entered.
        isValid = checkFailed(strfmt("The fiscal year is required. Enter a defined fiscal year to continue."));
    }
    else if (this.parmProjId() == '')
    {
        // Project ID was not entered.
        isValid = checkFailed(strfmt("The Project Id is required. Enter a defined Project Id to continue."));
    }
    return isValid;
}
