    Try the following... that work for me:

    UserKeysMD keyMd = (UserKeysMD)SboCompany.GetBusinessObject(BoObjectTypes.oUserKeys);
    keyMd.TableName = "TableName";
    keyMd.KeyName = "KeyName";
    keyMd.Elements.ColumnAlias = "Field"; 
    keyMd.Unique = BoYesNoEnum.tYES;

    Hi yash sharma

    Must amke sure the table and the field exists in that database, then do not put in your code the "@" symbol or the "U_" symbol. Also the field should not have dupliacte data.Once you have added the key look in OUKD, this is where sap stores the MDKeys.

    Here is sample code if you do it in vb

    Dim UserKey As SAPbobsCOM.UserKeysMD

    UserKey = oCompany.GetBusinessObject(SAPbobsCOM.BoObjectTypes.oUserKeys)


    UserKey.TableName = "SM_OPED"

    UserKey.KeyName = "test"

    UserKey.Elements.ColumnAlias = "Proc"

    UserKey.Unique = SAPbobsCOM.BoYesNoEnum.tYES

    lRetCode = UserKey.Add

    If lRetCode <> 0 Then

    oCompany.GetLastError(lRetCode, sErrMsg)


    End If

    Catch ex As Exception


    End Try

    The above works and adds one key.

    Hope this helps 😊

      I have a UDT whith a UDF created throw the SAP BO Application, and need to enforce a unique constraint.

      I used the sample code provided by Louis but

      the UserKet.Add returns error code

      -5002 : Invalid field name

      UserKey.TableName = "MGCF" 'The UDT Name

      UserKey.KeyName = "KeyCCode" 'The Key Name

      UserKey.Elements.ColumnAlias = "CCode" 'The Column Name

      UserKey.Unique = SAPbobsCOM.BoYesNoEnum.tYES

      What Have i done wroung?

      Thanks Pedro Gomes.

    Make sure the field's names you're indexing (then Elements.ColumnAlias) are less o equal than 8 characters (it gives me a lot of headaches...)

      I've deleted my UDT an created it again this time in code

      after i've added the UDF also in code

      the same error ocurres when i try to create the unique constraint

      code i used for creating the key.

      oUserKeysMD = oCompany.GetBusinessObject(SAPbobsCOM.BoObjectTypes.oUserKeys)

      oUserKeysMD.TableName = "MGCF"

      oUserKeysMD.KeyName = "Key_CCode"

      oUserKeysMD.Elements.ColumnAlias = "CCode"

      oUserKeysMD.Unique = SAPbobsCOM.BoYesNoEnum.tYES

      If oUserKeysMD.Add <> 0 Then


      End If

      if anyone cam spot the bug please let me know

      Thanks Pedro Gomes
