You attempted to access an unassigned field symbol
(data segment 32821).
This error may occur if
- You address a typed field symbol before it has been set with
- You address a field symbol that pointed to the line of an
internal table that was deleted
- You address a field symbol that was previously reset using
UNASSIGN or that pointed to a local field that no
- You address a global function interface, although the
respective function module is not active - that is, is
not in the list of active calls. The list of active calls
can be taken from this short dump.
