我正在使用 MVC 来管理 BMC 票证的提出和解决。但是，对于某些组，在将更改类型选择为“已解决”后会打开其他字段，我尝试了这些字段的输入值，但我仍然无法解决事件。下面是使用的代码，
StagingRequest.Incident_Nature = "NA";
StagingRequest.Network_Infrastructure = "NA";
StagingRequest.Incident_Element = "NA";
String ss = _WS1.HelpDesk_Modify(_AI1, StagingRequest.Incident_Number, StagingRequest.Type_of_Change, StagingRequest.Status_Reason, StagingRequest.Group_Name, StagingRequest.Assignee_Login_ID, StagingRequest.Resolution, StagingRequest.Incident_Nature, StagingRequest.Network_Infrastructure, StagingRequest.Incident_Element, StagingRequest.WorkLog_SupportDiary, StagingRequest.Work_Info_Notes, StagingRequest.Expiry_Date);
请注意，我尝试在这 3 个字段中输入实际下拉值仍然是相同的错误“无法修改：错误（100000308）：；请在解决票证之前选择以下字段的值；“事件性质”，“网络基础设施”和‘事件要素’。”
不需要其他字段的其他组使用以下代码，
String ss = _WS1.HelpDesk_Modify(_AI1, StagingRequest.Incident_Number, StagingRequest.Type_of_Change, StagingRequest.Status_Reason, StagingRequest.Group_Name, StagingRequest.Assignee_Login_ID, StagingRequest.Resolution, null, StagingRequest.Cause_for_SLA_Violation, StagingRequest.SLA_Comments, StagingRequest.WorkLog_SupportDiary, StagingRequest.Work_Info_Notes, StagingRequest.Expiry_Date);
