unexpected behaivor setting UserFieldsMD.LinkedTable property

He all

I have a user form created for maintain a group o userfields added to the OITM table (object 4). The form property Object type, in design tame, was set to 4 and AutoManaged property to true.

Three fields are referenced to another user tables (with their UDO and type MasterData) with the property LinkedTable.

When the form obtains the info in these three fields referenced I see the "ItemCode" value writo into.

If I not stablish the property LinkedTable the form runs ok, showing the values of the fields well, updating and loading data from db. But there is not a good solution but I lost the referential integritiy.

Any idee about this? I have omited any step? This is a bug? A limitation?

Thanks in advance
