ALV GRID IS NOT WORKING

[former_member623843]

HI every one,

I want to dispaly alv grid. but i came to know that without designing fieldcat by using the below FM we can display the output in grid formate..buut i didn't grid formate by using the below code..

can any one tell me the wayy.

REPORT Z3MGLALV21.

TYPE-POOLS: slis.

DATA: BEGIN OF itab OCCURS 0,

matnr(18),

werks(4),

ekgrp(3),

END OF itab.

DATA: i_fieldcat TYPE TABLE OF slis_fieldcat_alv,

w_fieldcat TYPE slis_fieldcat_alv.

SELECT matnr

werks

ekgrp

FROM marc

INTO TABLE itab.

• WHERE WERKS = '1000'.

CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'

EXPORTING

I_PROGRAM_NAME = SY-CPROG

I_INTERNAL_TABNAME = 'ITAB'

• I_STRUCTURE_NAME =

• I_CLIENT_NEVER_DISPLAY = 'X'

I_INCLNAME = sy-cprog

• I_BYPASSING_BUFFER =

• I_BUFFER_ACTIVE =

CHANGING

ct_fieldcat = i_fieldcat

• EXCEPTIONS

• INCONSISTENT_INTERFACE = 1

• PROGRAM_ERROR = 2

• OTHERS = 3

.

IF sy-subrc <> 0.

• MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO

• WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.

ENDIF.

you are not calling the ALV function at all , how it will display..?

TYPE-POOLS: slis.

DATA: BEGIN OF itab OCCURS 0,
      matnr LIKE mara-matnr,
      werks LIKE marc-werks,
      ekgrp LIKE marc-ekgrp,
      END OF itab.

DATA: i_fieldcat TYPE TABLE OF slis_fieldcat_alv,
w_fieldcat TYPE slis_fieldcat_alv.

SELECT matnr
      werks
      ekgrp
FROM marc
INTO TABLE itab.



CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'
  EXPORTING
    i_program_name         = sy-repid
    i_internal_tabname     = 'ITAB'
    i_inclname             = sy-repid
  CHANGING
    ct_fieldcat            = i_fieldcat
  EXCEPTIONS
    inconsistent_interface = 1
    program_error          = 2
    OTHERS                 = 3.
IF sy-subrc NE 0.

  MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
  WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
ENDIF.

CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
  EXPORTING
    i_callback_program = sy-repid
    it_fieldcat        = i_fieldcat
  TABLES
    t_outtab           = itab
  EXCEPTIONS
    program_error      = 1.

Hai try this one

type-pools: slis.

Data: begin of it_mara occurs 2,

matnr like mara-matnr, "material Number

meins like mara-meins, "Bse unit of measurement

ersda like mara-ersda, " on which date was created

end of it_mara,

Data: i_fieldcat type slis_t_fieldcat_alv.

select

matnr "material Number

meins "Bse unit of measurement

ersda " on which date was created

into table it_mara

call function module

ALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'

EXPORTING

i_program_name = sy-repid

i_internal_tabname = 'It_mara'

i_inclname = sy-repid

CHANGING

ct_fieldcat = i_fieldcat

EXCEPTIONS

inconsistent_interface = 1

program_error = 2

OTHERS = 3.

IF sy-subrc NE 0.

MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno

WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.

ENDIF.

CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'

EXPORTING

i_callback_program = sy-repid

it_fieldcat = i_fieldcat

TABLES

t_outtab = it_mara

EXCEPTIONS

program_error = 1.

Hi,

my dear friend.for displaying the output in alv grid format u have to use CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY' along with what u have used.so try as below,u'l definitely get the output

TYPE-POOLS: slis.

DATA: BEGIN OF itab OCCURS 0,

matnr LIKE mara-matnr,

werks LIKE marc-werks,

ekgrp LIKE marc-ekgrp,

END OF itab.

DATA: i_fieldcat TYPE TABLE OF slis_fieldcat_alv,

w_fieldcat TYPE slis_fieldcat_alv.

SELECT matnr

werks

ekgrp

FROM marc

INTO TABLE itab.

CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'

EXPORTING

i_program_name = sy-repid

i_internal_tabname = 'itab'

i_inclname = sy-repid

CHANGING

ct_fieldcat = i_fieldcat

EXCEPTIONS

inconsistent_interface = 1

program_error = 2

OTHERS = 3.

IF sy-subrc NE 0.

MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno

WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.

ENDIF.

CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'

EXPORTING

i_callback_program = sy-repid

it_fieldcat = i_fieldcat

TABLES

t_outtab = itab(internal table)

EXCEPTIONS

program_error = 1.

Hi Mahaboob,

Function Moudle

  'REUSE_ALV_FIELDCATALOG_MERGE'  

the structure which you are passing to create a field catalog should be present inthe DDIC. Then only it will automatically it will create a field catalog.

You need to call the Function Module

 REUSE_ALV_GRID_DISPLAY 

. otherwise you would not be able to display the ALV on the output.

Thanks,

Hi Mehaboob,

First try to under what you are doing and how you are coding and what effect will have on the output if u write anything please this follow this steps to become a good programmer.

You are saying i want to display report in ALV grid and there is no declaration for grid formate (REUSE_ALV_GRID_DISPLAY) how will you get then.

All the above posts are helpful to achieve your issue go ahead.

My suggestion try till your level and then you post.

Cheers!!

Hi all,

I have run this program and it is working fine. But this same logic when I used in other program I am getting dump.

The dump location is:

FM: K_KKB_FIELDCAT_MERGE

Line number: 336

Read report l_prog_tab_local into l_abap_source.

Please tell me what to do..

[former_member188685]

may be you hardcoded the program name. which is not there. check it once. use sy-repid/sy-cprog where ever you want to refer the program name. i am sure the mistake is in that place.

[former_member623843]

No vijay,

Here the problem was, for the last line i have wrote 80 char.

Now my code is wroking..

[former_member188685]

great, finally you solved it.

[former_member623843]

Thanks
