Error analysis
    An attempt was made to access a field symbol that has not been assigned
    yet (data segment number "-1").

    That error occurs if
    - a typed field symbol is addressed before it has been set with ASSIGN,
    or
    - a field symbol is addressed that points to a row in an internal table
    that has been deleted, or
    - a field symbol is addressed that was previously reset using UNASSIGN,
    or that pointed to a local field that no longer exists, or
    - a parameter of a global function interface is address, although the
    corresponding function module is not active (is not in the list of
    active calls). The list of active calls can be taken from this short
    dump.
