I get this error when I try to use table relation with filters 
Microsoft.Dynamics.Nav.Types.DBLazy  it is not the error itself but it is being inserted in the field instead of the value 
Can any one help me?

    I get an error when I use table relation with filters
    The error is still present in BC24.5.
     
    Steps for reproducing:
    Create a table field with a table relation to another table and to a field outside the primary key. The TableRelation must be set to false.
    Insert the field into a page object.
     
    Example:
field(10; ‘Additional Field’; Code[10])
{
    Caption = ‘Additional Field’;
    TableRelation = ‘Location’. ‘Additional Field’;
    ValidateTableRelation = false;
 }
     
    If you now try to make a selection via drilldown, you receive the error ‘Microsoft.Dynamics.Nav.Types.DBLazy’
    If you use the ‘Show full List’ function for selection, the expected value will be applied.
     
    Solution:
    The error can be avoided if the required field is added to the drilldown page of the corresponding table. The field does not even have to be visible.
     
    Example:
    pageextension 50000 ‘Location List’ extends ‘Location List’
{
    layout
    {
        addlast(Control1)
        {

            field(‘Additional Identifier’; Rec. ‘Additional Identifier’)
            {
                ApplicationArea = All;
                Visble = false;
            }
        }
    }
}
    I hope I was able to help you with this.
    Happy Coding

    I solved this by using OnLookup trigger, still could not figure out what was the problem

    but here is the Code

    field(5; "Requester"; code[20])

           {

               DataClassification = ToBeClassified;

               TableRelation = Requester.OnBehalf where("User Name" = field(Preparer), Status = const(Approved));

               ValidateTableRelation = false;

    }

    Maybe you can try to share your code, then it is easier to assist you in cases like this.

    Or at least elaborate a little more about what you are trying to do and from where?
