Issues when building ALV catalog

[Former Member]

Hello experts,

I am using the following function module to build my ALV catalog:

CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'
    EXPORTING
      i_program_name     = 'ZLRLEXC_QUANTS_X_MATERIAL'
      i_internal_tabname = 'ALV_ITAB'
      i_inclname         = 'ZLRLEXC_QUANTS_X_MATERIAL_TOP'
    CHANGING
      ct_fieldcat        = field.
  IF sy-subrc <> 0.
    WRITE: 'SY-SUBRC: ', sy-subrc, 'REUSE_ALV_FIELDCATALOG_MERGE'.
  ENDIF.

The problem that I'm facing is that the "field" internal table does not contain any information after processing, and the odd thing is that sy-subrc = 0.

Any help would be highly appreciate it!

Regards,

how are field and alv_itab defined?

use like this:

DATA:  lt_fieldcat TYPE slis_t_fieldcat_alv.
CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'
    EXPORTING
      i_program_name         = sy-repid
      i_structure_name       = 'FAGL_S_RFBELJ10_COMPANY_CODES'
    CHANGING
      ct_fieldcat            = lt_fieldcat
    EXCEPTIONS
      inconsistent_interface = 1
      program_error          = 2
      OTHERS

it should work.

data: v_repid type sy-repid.

v_repid = 'ZLRLEXC_QUANTS_X_MATERIAL_TOP'

CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'
    EXPORTING
      i_program_name     = SY-REPID
      i_internal_tabname = 'ALV_ITAB'
      i_inclname            =  V_REPID
    CHANGING
      ct_fieldcat        = field.
  IF sy-subrc  0.
    WRITE: 'SY-SUBRC: ', sy-subrc, 'REUSE_ALV_FIELDCATALOG_MERGE'.
  ENDIF.

All the Internal tables field should be defined using LIKE

you should define in the below mentioned way...

Data: begin of itab occurs 0,
           matnr like mara-matnr,  
         end of itab.

Thanks Vijay... you nailed the issue.. I was using "type" instead of "like" when creating the ALV_ITAB internal table.

Thanks everyone for you input!

hi did you defield like this..

data: alv_itab type SLIS_TABNAME .

data: ZLRLEXC_QUANTS_X_MATERIAL_TOP type TRDIR-NAME .

data: field type SLIS_T_FIELDCAT_ALV .
