Runtime error while executing ALV

[Former Member]

Hi all,

I have implemented an ALV in OOPS concept and whenevr I am executing it I am getting a runtime error as GET WA NOT ASSIGNED

Error analysis:

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

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.

This is my code.

When i execute it without any values in my final table the ALV is getting displayed.

But when I put some data in the final table I am getting this error

[former_member188827]

make sure dat constants which u r using to specify field names hold names in CAPS..i.e all field names should be in capital letters.

if dis doesnt help, try replacing constants by actual field names in capital letters and enclosed in single quotes..
