alv runtime error

[Former Member]

Hallow I do a simple alv report that I take from se 83 example

And I have RUNTIME ERROR what it can be

What I doing wrong mybe I forget somtihg .

<b>This is the

Error analysis</b>

You attempted to access an unassigned field symbol

(data segment 32820).

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.

Hello,

U need to assign the field symbol to any structure before u process the field symbol.

Like this

<b>1. ASSIGN f TO <fs>.

2. ASSIGN COMPONENT idx/name OF STRUCTURE struc TO <fs>.

3. ASSIGN LOCAL COPY OF ... f TO<fs>.

4. Dynamic ASSIGN

a. ASSIGN (f) TO <fs>.

b. ASSIGN TABLE FIELD (f) TO <fs>.

c. ASSIGN LOCAL COPY OF MAIN TABLE FIELD (f) TO <fs>.

d. ASSIGN LOCAL COPY OF ... (f) TO <fs>.

5. ASSIGN dref->* TO <fs>.</b>

If useful reward.

Hello Antonio,

if g_gui_type ne 1.

if <ls_fcat>-key eq abap_true.

ls_lvc_data-style = alv_style_color_int_key.

elseif l_style_color is initial

and ( <ls_fcat>-emphasize is initial or

<ls_fcat>-emphasize = '$' ).

if <ls_stin>-counter is initial.

ls_lvc_data-style = alv_style_color_normal.

In the above piece of code first u need to assign the field symbol

assign str to <ls_fcat>.

If u do this u won't get the short dump.

If useful reward.

hi Vasanth M i have to copy that to my program as is ?.i ask that becouse i never use a field symbol . and if i have to change your code which things i have to change regards

[Former Member]

hi vasanth what i have to put in ls_fcat regards

Hi,

To declare a field symbol, use the statement

FIELD-SYMBOLS <FS> [<type>|STRUCTURE <s> DEFAULT <wa>].

For field symbols, the angle brackets are part of the syntax. They identify field symbols in the program code.

If you do not specify any additions, the field symbol <FS> can have data objects of any type assigned to it. When you assign a data object, the field symbol inherits its technical attributes. The data type of the assigned data object becomes the actual data type of the field symbol.

Check the sample code:

TYPES: BEGIN OF line,

col1 TYPE c,

col2 TYPE c,

END OF line.

DATA: wa TYPE line,

itab TYPE HASHED TABLE OF line WITH UNIQUE KEY col1,

key(4) TYPE c VALUE 'COL1'.

FIELD-SYMBOLS <fs> TYPE ANY TABLE.

ASSIGN itab TO <fs>.

READ TABLE <fs> WITH TABLE KEY (key) = 'X' INTO wa.

Hope this helps.

hi keerthi kiran varanasi why i have to do that i dont use field symbol in my program regards

[alison_lloyd]

field symbol errors in ALV are usually down to fieldcat columns incorrectly defined. Check your internal table fields of the table you pass to the alv FM against the columns defined in the fieldcat
