Error when trying to update UserField in 9.0 PL11

Question

Hi experts,
I'm currently tring to update userfield in the table ORDR,RDR1,OWTR and WTR1 using the DI API and each time an error occurs.
For the ORDR and OWTR table the error description is
Cannot drop the index 'dbo.OIEI.OIEIMRO_SO', because it does not exist or you do not have permission
For the RDR1 and WTR1 table the error description is
Cannot drop the index 'dbo.IEI1.IEI1MRO_SO', because it does not exist or you do not have permission
Do you know why this error occurs and why sap try to drop an index in the table OIEI or IEI1 when i'm updating a field in ORDR or RDR1?
Thanks.
Best regards

hi.
you have to use get by key method for updating the user defined fields..like below..
sales order i am upating.
    Dim vOrder As SAPbobsCOM.Documents
                    vOrder = oCompany.GetBusinessObject(SAPbobsCOM.BoObjectTypes.oOrders)
              Dim s As String
                    If vOrder.GetByKey(150) Then
'here  150 is the  doc entry i am going to update the  fields.
Header:
oDocument.UserFields.Fields.Item("U_XYZ").Value = "Test";
Line:
oDocument.Lines.UserFields.Fields.Item("U_XYZ").Value = "Test;
Somet times you have to convert it to string.
myVar = oDocument.UserFields.Fields.Item("U_XYZ").Value.ToString();
MessageBox.Show(s)
                    End If
