Short dump has not been completely stored (too big)

Short text

Field symbol has not yet been assigned.

What happened?

Error in the ABAP Application Program

The current ABAP program "SAPLKKBL" had to be terminated because it has

come across a statement that unfortunately cannot be executed.

Error analysis

You attempted to access an unassigned field symbol

(data segment 106).

This error may occur if

- You address a typed field symbol before it has been set with

ASSIGN

- 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

longer exists

- 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.
