LVC_FIELDCATALOG_MERGE with internal table

[eyal_alsheikh]

Hi,

Can I use Function Module LVC_FIELDCATALOG_MERGE to get the fieldcatalog of the global internal table in my program instead of dictionary table.

Using parameter i_internal_tabname instead of i_structure_name doesn't work.

Thanks,

Eyal.

Hi

This fm doesn't work by internal table, you have to pass only dictionary table, but you can use REUSE_ALV_FIELDCATALOG_MERGE:

TYPE-POOL SLIS:

DATA: GT_FIELDCAT TYPE SLIS_T_FIELDCAT_ALV,

LT_FIELDCAT TYPE SLIS_FIELDCAT_ALV,

GT_LVC_FIELDCAT TYPE LVC_T_FCAT,

LT_LVC_FIELDCAT TYPE LVC_S_FCAT.

CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'

EXPORTING

I_PROGRAM_NAME = GT_REPID

I_INTERNAL_TABNAME = 'ITAB'

I_INCLNAME = GT_REPID

CHANGING

CT_FIELDCAT = GT_FIELDCAT.

LOOP AT GT_FIELDCAT INTO LT_FIELDCAT.

MOVE-CORRESPONDING LT_FIELDCAT TO LT_LVC_FIELDCAT.

APPEND LT_LVC_FIELDCAT TO GT_LVC_FIELDCAT.

ENDLOOP.

Eyal,

I don't think you can do that ?

can you paste the code you have for the call method with the NAME OF THE STRUCTURE?

Check this

In PBO,

*   Building the field catalog
    PERFORM f9001_build_field_cat TABLES i_fieldcat
                            USING 'ZCSA_MARKETIING_EXPENSE_OUTPUT'

FORM f9001_build_field_cat TABLES   p_fieldcat STRUCTURE lvc_s_fcat
                      USING value(p_structure).

  CALL FUNCTION 'LVC_FIELDCATALOG_MERGE'
       EXPORTING
            i_structure_name       = p_structure
       CHANGING
            ct_fieldcat            = p_fieldcat[]
       EXCEPTIONS
            inconsistent_interface = 1
            program_error          = 2
            OTHERS                 = 3.
  IF sy-subrc <> 0.
    MESSAGE i013 WITH text-e05."Error in ALV field catalogue creation
    LEAVE LIST-PROCESSING.
  ENDIF.

ENDFORM.                    " f9001_build_field_cat

U can create a structure or example pass MARA then it will take the structure of MARA.

Hi,

In the function module attribute SAP wrote:

Create field catalog from dictionary structure or <b>internal table</b>

So maybe there is a way,

Thanks,

you can do that . check the following code sample.

 move: sy-repid to wf_repid  ,
        'INT_OUTPUT' to int_tab_name . 
* INT_OUTPUT is the name of the internal table (use upper case)

  call function 'REUSE_ALV_FIELDCATALOG_MERGE'
   exporting
     i_program_name              = wf_repid
     i_internal_tabname          = int_tab_name
*   I_STRUCTURE_NAME             =
*   I_CLIENT_NEVER_DISPLAY       = 'X'
    i_inclname                   = wf_repid
    i_bypassing_buffer           = 'X'
*   I_BUFFER_ACTIVE              =
    changing
      ct_fieldcat                  = wf_fld_cat[]
   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.

Hi Eyal,

If you check this function module code the parameter I_INTERNAL_TABNAME is not used anywhere. So it would be better to use 'REUSE_ALV_FIELDCATALOG_MERGE'.

If I check the function code of

'REUSE_ALV_FIELDCATALOG_MERGE'

if ( i_structure_name is initial )

and ( i_internal_tabname ne space ).

" called with internal table

"( not supported, see documentation)

It seems it is not supported
