field symbol has not yet been assigned, ALV

[Former Member]

The error is this:

Field symbol has not yet been assigned.

Error in the ABAP Application Program

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

come across a statement that unfortunately cannot be executed.

When I want to display the data with alav grid, I could not achieve it and got the error described above.

What is the cause of this problem?

Thanks.

Hi

That dump is usually triggered when something of the ALV structures is wrong.

U should check how you fill the catalog table.

Hi,

As correctly pointed out by the previous post, Problem will definately be with the fieldcatalog. Please check the fieldname defined in fieldcatalog & internal table are matching. Please also note that in field catalog field names MUST BE in CAPITALS.

I still your problem is not solved follow the followinf procedure to fix the problem.

Suppose you have got 5 fields which you are dispalying in ALV then comment out fieldcatalog enteries of 4 fields & check. If you do not get the dump that implies this field is OK. Now uncomment the fieldcatalog enteries of the second field & check if you get a dump. If no follow the same procedure with the remaining field till you get a dump. Rest is easy. In case you have got lot of fields you may use the above approach with a group of say 5 to 7 fields, & once group is fixed follow the above procedure to fix the field.

I hope this helps,

Thanks for your explanation.. It was useful to me. My fieldname was in lowercase;

Field catalog is used to display report data in output of alv, Fcat will creates columns in ALV.

when u are calling REusealvhere u have a option to call Fcat as a export parameter.

<b> fcat-fieldname = 'FDTM'.

fcat-hotspot = ' '.

fcat-no_zero = 'X'.

fcat-just = 'R'.

fcat-seltext_l = 'Filler D/T'.

fcat-ddictxt = 'L'.

fcat-inttype = 'P'.

fcat-datatype = 'QUAN'.

append fcat.

clear fcat.</b>

<b>call function 'REUSE_ALV_LIST_DISPLAY'

exporting

i_callback_program = lv_repid

• i_callback_user_command = 'Z_USER_COMMAND'

is_layout = fs_layo

it_fieldcat = fcat[]

it_sort = fsort[]

• I_CALLBACK_PF_STATUS_SET = g_statu_07

i_default = 'X'

i_save = 'U'

it_events = fevents[]

tables

t_outtab = itab_order2[].</b>

Hi,

I think that you have provided incomplete fieldcatalog information for your ALV .

Try to use function modules to build field catalog instead of doing mannually.

REUSE_ALV_FIELDCATALOG_MERGE (Using REUSE* fm)

LVC_FIELDCATALOG_MERGE (Using OOp)

Hi,

I had got the same problem previously. It is the problem with incorrect assignment. I had changed the code as below:

REPORT ZYKTEST3 .

DATA: d_ref TYPE REF TO data,

d_ref2 TYPE REF TO data,

i_alv_cat TYPE TABLE OF lvc_s_fcat,

ls_alv_cat LIKE LINE OF i_alv_cat.

TYPES: tabname LIKE dcobjdef-name ,

fieldname LIKE dcobjdef-name,

desc LIKE dntab-fieldtext.

PARAMETER: p_tablen TYPE tabname.

DATA: BEGIN OF itab OCCURS 0.

INCLUDE STRUCTURE dntab.

DATA: END OF itab.

FIELD-SYMBOLS : <f_fs> TYPE table,

<f_fs1> TYPE table,

<f_fs2> TYPE ANY,

<f_fs3> TYPE ANY,

<f_fs4> type any,

<f_field> TYPE ANY.

REFRESH itab.

CALL FUNCTION 'NAMETAB_GET'

EXPORTING

langu = sy-langu

tabname = p_tablen

TABLES

nametab = itab

EXCEPTIONS

no_texts_found = 1.

LOOP AT itab .

ls_alv_cat-fieldname = itab-fieldname.

ls_alv_cat-ref_table = p_tablen.

ls_alv_cat-ref_field = itab-fieldname.

ls_alv_cat-seltext = itab-fieldtext.

ls_alv_cat-reptext = itab-fieldtext.

APPEND ls_alv_cat TO i_alv_cat.

ENDLOOP.

• internal table build

CALL METHOD cl_alv_table_create=>create_dynamic_table

EXPORTING

it_fieldcatalog = i_alv_cat

IMPORTING

ep_table = d_ref.

ASSIGN d_ref->* TO <f_fs>.

DATA: l_field TYPE fieldname,

l_field1 type fieldname.

SELECT * FROM (p_tablen) INTO CORRESPONDING FIELDS OF TABLE <f_fs>.

LOOP AT <f_fs> ASSIGNING <f_fs2>.

ASSIGN COMPONENT 2 OF STRUCTURE <f_fs2> TO <f_fs3>.

ASSIGN COMPONENT 3 OF STRUCTURE <f_fs2> TO <f_fs4>.

IF sy-subrc = 0.

MOVE <f_fs3> TO l_field.

MOVE <f_fs4> TO l_field1.

WRITE:/1 l_field(20),

22 l_field1(10).

ENDIF.

ENDLOOP.

Hi,

Change the field name in ALV field category into caps.

Example:

wa_alv_fieldcat-fieldname = 'object_id'

INTO

wa_alv_fieldcat-fieldname = 'OBJECT_ID'
