Hi, guys, One of my clients was required by the hospital to name their webservice operation as Action\_Subject, ie. Get\_PatientInfo When I define the web method as "Get_PatientInfo" as below, /// MyApp.MyService Class MyApp.MyService Extends %SOAP.WebService [ ProcedureBlock ] { /// Name of the WebService. Parameter SERVICENAME = "MyService"; /// TODO: change this to actual SOAP namespace. /// SOAP Namespace for the WebService Parameter NAMESPACE = "http://tempuri.org"; /// Namespaces of referenced classes will be used in the WSDL. Parameter USECLASSNAMESPACES = 1; /// TODO: add arguments and implementation. /// Test Method "Get_PatientInfo"() As %String [ WebMethod ] {     Quit "Test" } } the code can not be compiled because of the following error: Compilation started on 06/04/2018 12:48:09 with qualifiers 'cuk /checkuptodate=expandedonly' Compiling class MyApp.MyService ERROR #5802: Datatype validation failed on property '%Dictionary.ClassDefinition:IsValid', with value equal to "MyApp.MyService.Get_PatientInfo"   > ERROR #5802: Datatype validation failed on property '%Dictionary.ClassDefinition:Name', with value equal to "MyApp.MyService.Get_PatientInfo"     > ERROR #5490: Error running generator for method 'OnCompile:MyApp.MyService'  ERROR: %SOAP.WebBase.cls(OnCompile) of generated code compiling subclass 'MyApp.MyService'       > ERROR #5030: An error occurred while compiling class 'MyApp.MyService' Compiling routine MyApp.MyService.1 If we can not name the method as required, is there any other way to do that? Thanks.
