I am getting this error in tabular form which is to be populated by selecting an item called week description in that page through a dynamic action.
In main table I have two primary keys and so two foreign keys in detail table even though it is not a type of master detail form.
when I select week description item and related records in tabular form to be shown.But it is giving above error.
In main table there are two same records ,in that records user name is different that defines the unique ness of record.
