UDO registration through COde

Hi

I m unable to do registration of UDO through code.

I m having two tables.1. U_UDOM(Master) and the second one is U_UDOC(Child). As i add my UDO, after assigning all properties it gives me error code(-<b>50002</b>). Can u help me regarding this error???

Also i want to know these properties of SAPbobsCOM.UserObjectsMD(i mean what values we should assign to these properties)

oUserObjectMD.Code = "EMPID";

oUserObjectMD.ManageSeries = SAPbobsCOM.BoYesNoEnum.tYES;

oUserObjectMD.Name = "EMPNAME";
