        public static SAPbobsCOM.Company oCompany = null;
        public SBOMain()
        {
            try
            {
                SetApplication();
                SetConnection();
                SBO_Application.StatusBar.SetText("Add on Sample Connected !", SAPbouiCOM.BoMessageTime.bmt_Short, SAPbouiCOM.BoStatusBarMessageType.smt_Success);

            }
            catch (Exception)
            {

Thanks

The error you're encountering, "SBOMain() must have a return type," is likely due to a typo in your class name. The class name should match the constructor name exactly, including case sensitivity. In your code, the class is named SBoMain , but the constructor is named SBOMain . Changing the class name to SBOMain should resolve the issue: class SBOMain { public static SAPbouiCOM.Application SBO_Application; public static SAPbobsCOM.Company oCompany = null; public SBOMain() { try { SetApplication(); SetConnection(); SBO_Application.StatusBar.SetText("Add on Sample Connected !", SAPbouiCOM.BoMessageTime.bmt_Short, SAPbouiCOM.BoStatusBarMessageType.smt_Success); } catch (Exception) { throw; } } } Give this a try and let me know if it resolves the error! Thanks

The error you're seeing, SBOMain() must have a return type , occurs because in C#, constructors must not declare a return type, not even void . However, if the SBOMain is intended to be a constructor, the class name ( SBoMain ) and the constructor name must match exactly, including casing. Your constructor is written as SBOMain() , while your class name is SBoMain . C# is case-sensitive, so this mismatch will result in the method being treated as a regular method instead of a constructor, and since regular methods must have a return type, the error occurs. Solution Change the constructor name to match the class name exactly: class SBoMain { public static SAPbouiCOM.Application SBO_Application; public static SAPbobsCOM.Company oCompany = null; public SBoMain() // Corrected constructor name to match the class name { try { SetApplication(); SetConnection(); SBO_Application.StatusBar.SetText( "Add-on Sample Connected!", SAPbouiCOM.BoMessageTime.bmt_Short, SAPbouiCOM.BoStatusBarMessageType.smt_Success ); } catch (Exception) { throw; } } } Explanation The name SBoMain must match for the constructor and the class. A constructor does not have a return type (not even void ). The corrected constructor will initialize the class when an object of SBoMain is created. This should resolve the issue.
