REUSE_ALV_LIST_DISPLAY' Field symbol has not yet been assigned.

[Former Member]

Hi Dear All.

My ALV is working well when the internal table is initial,

but if i assign some vale to internal table, it raises short dump...

You attempted to access an unassigned field symbol

(data segment 92).

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.

===================================================

I've checked my fieldcatlog and table sturcture.

and no sort table , no filterr table.

Did i miss something ?

Thank you all
