Problem creating User Defined Table

Question

I am using C# and SBO 6.5
Error Code: -1120
Error Message: "The Mete Data for this object cannot be updated,\nsince it's ref count is bigger then 0."
SAPbobsCOM.UserTablesMD m;
                    m = (SAPbobsCOM.UserTablesMD)
                              frmMain.oCompany.GetBusinessObject(SAPbobsCOM.BoObjectTypes.oUserTables);
if (m.GetByKey("CBtr")==false)
m.TableName="CBtr";
                              m.TableDescription = "TEST";
fieldadded =m.Add();
if (fieldadded !=0)
frmMain.oCompany.GetLastError(out oErrorCode,out oError);
Any help is appreciated.
Thanks,
Gopal

Hi Gopal,
Please note that GetByKey on a meta data object already makes it necessary to release the object (in your case "m").
In general you should use .NET's ReleaseCOMObject (see here:
SBO-SDK Consult : Releasing COM Object in .NET) to get rid of the "reference", but note that you most likely will have to set the object variable to null.
Alternatively setting the variable to null + a call to GC.Collect() might could do the trick, but GC.Collect() apparently works asynchronously! So, the COM object might not really have been released yet when you try to reuse the variable. GC.WaitForPendingFinalizers might work better.
