You really need to be more specific with your question.  The subject says something about field symbols not being assigned, but after looking at your code, you don't even have a field symbol defined, let alone assigned. 

If you don't modify this post soon, the mods will lock it.

hi

   when i am trying to execute te above program i am getting this run time error as

this error is generating when i execute my program

Field symbol has not yet been assigned.

Error in the ABAP Application Program

  The current ABAP program "SAPLSLVC" had to be terminated because i

come across a statement that unfortunately cannot be executed.

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.

but i have not taken any field symbol

This message is raised by standard ALV as it try to interpret your data, so some field name  should not be correct (layout, field catalog and other)

- check that the fields of the field catalog exist in the internal table (lowercase, typo, etc.)

- check that the fields mentioned in the layout (box, light name, etc.) also exist in the internal table

- if you are able to display the ALV, perform The Consistency Check

Hi Tej,

While going through the code, I found that the fields which are used in the ALV Layout i.e., (RC & LIGHTS) are not added to the Field Catalog. Since the field, which is not present in the Field Catalog, is addressed in the Layout Properties, the system is resulting in a Dump.

Create the Field Catalog entry for these two mentioned fields and rerun the Program. I hope your issue will get resolved.

Regards,

Chakra

Comment with * the line:

        I_STRUCTURE_NAME              = 'ZMYVBAK'

ZMYVBAK  # lt_vbak[] ( it_vbak has 2 extra field ->  RC and lights ).

See the program: BCALV_GRID_04

Check your fieldcatalog. You probably must have mistyped some field or missed some field.
