ALV Display Help using field catalog merge

[Former Member]

Hi All,

I am using the FM

call function 'REUSE_ALV_FIELDCATALOG_MERGE'

exporting

i_program_name = lv_repid

i_internal_tabname = 'GT_FINAL'

i_structure_name = 'Z_BIL_R_R0111_STR'

i_inclname = lv_repid

i_bypassing_buffer = lvc_yes

changing

ct_fieldcat = lt_fieldcat.

to papulate the fieldcat.

When i am manully papulating the Field catalog i am able to dispaly al the fields but when use *REUSE_ALV_FIELDCATALOG_MERGE

*THE FM 'REUSE_ALV_GRID_DISPLAY' goes to dump and im not able to figure out the problem.

I am using as below

• Call the ALV function module for list display

CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'

EXPORTING

i_callback_program = lv_repid

i_callback_user_command = 'USER_COMMAND'

i_callback_top_of_page = 'TOP_OF_PAGE'

it_fieldcat = lt_fieldcat

is_layout = ls_layout

TABLES

t_outtab = p_it_final.

In error analysis i get only this message

*You attempted to access an unassigned field symbol*

*(data segment "-1").* This error may occur if

- You address a typed field symbol before it has been set w

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 usin

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.

may i know the solution for the above.

Thanks,

Hi,

Its only because of Fieldcatalog problem.

Only one thing you need to take care is that when you refer any dictionary field do not use TYPE Instead use LIKE statement, then It works.

You can have a example..

TYPE-POOLS: SLIS.
*
DATA: PROGNAME  LIKE SY-REPID,
      GT_FCAT0  TYPE SLIS_T_FIELDCAT_ALV,
      GT_FCAT1  TYPE SLIS_T_FIELDCAT_ALV.
*
DATA: IT_MARA0 TYPE TABLE OF MARA.
*
DATA: BEGIN OF IT_MARA1 OCCURS 0,
         MATNR LIKE MARA-MATNR,
         MATKL LIKE MARA-MATKL,
       END   OF IT_MARA1.
*
PROGNAME  = SY-REPID.
* internal table definition with type of a structure
CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'
  EXPORTING
    I_PROGRAM_NAME         = PROGNAME
    I_INTERNAL_TABNAME     = 'IT_MARA0'
    I_STRUCTURE_NAME       = 'MARA'
    I_CLIENT_NEVER_DISPLAY = 'X'
  CHANGING
    CT_FIELDCAT            = GT_FCAT0[]
  EXCEPTIONS
    INCONSISTENT_INTERFACE = 1
    PROGRAM_ERROR          = 2
    OTHERS                 = 3.
* own internal table definition
CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'
  EXPORTING
    I_PROGRAM_NAME         = PROGNAME
    I_INTERNAL_TABNAME     = 'IT_MARA1'
    I_INCLNAME             = PROGNAME
    I_CLIENT_NEVER_DISPLAY = 'X'
  CHANGING
    CT_FIELDCAT            = GT_FCAT1[]
  EXCEPTIONS
    INCONSISTENT_INTERFACE = 1
    PROGRAM_ERROR          = 2
    OTHERS                 = 3.

Hello,

If 'Z_BIL_R_R0111_STR' is a DDIC structure & GT_FINAL is an internal table of 'Z_BIL_R_R0111_STR' structure, then just comment out the line I_INTERNAL_TABNAME & your fieldcat should get generated:

call function 'REUSE_ALV_FIELDCATALOG_MERGE'
exporting
i_program_name = lv_repid
* i_internal_tabname = 'GT_FINAL' "--> Comment out this line
i_structure_name = 'Z_BIL_R_R0111_STR'
i_inclname = lv_repid
i_bypassing_buffer = lvc_yes
changing
ct_fieldcat = lt_fieldcat.

BR,

Suhas
