Unable to insert Activity record

Question

Hi, I am using the webservice to insert a new Activity record.
Step 1: I created a insert object with "ActivityNWS_Activity_Insert_Input",
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
WSOD_Activity.ActivityNWS_Activity_Insert_Input insActObj = new WSOD_Activity.ActivityNWS_Activity_Insert_Input();
WSOD_Activity.ActivityNWS_Activity_Insert_Output outputActObj = new WSOD_Activity.ActivityNWS_Activity_Insert_Output();
insActObj.ListOfActivity = new WSOD_Activity.Activity1[1];
insActObj.ListOfActivity[0] = new WSOD_Activity.Activity1();
..... assigning values to the fields .......
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
Step 2: I call the function "Activity_Insert", it returns an "ActivityNWS_Activity_InsertChild_Output" object.
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
WSOD_Activity.Activity prxySrvcActivity = new WSOD_Activity.Activity();
prxySrvcActivity.Url = GlobalVariables.mSession.GetURL();
prxySrvcActivity.CookieContainer = GlobalVariables.mSession.GetCookieContainer();
outputActObj = prxySrvcActivity.Activity_Insert(insActObj);
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
When I check the output object, most of attributes are empty, (include the end time, start time, status & type), but the ActivityID and Created By is filled with content.
Next I checked the webservice utilization from the SoD page, there is a insert record showing the transaction has no error.
But when I search the Activity module, I could not find any records.
When I tried using WSDL 2.0 and do the above again, I got the same result.
What's wrong with that ? Could anyone please help me ?

Answer 1

I wounder if I should assign "" to the "ActivityId" when doing insertion or what else............
Has anyone tried this before ?
