Hi,

this function modue will automatically create the fieldcatalog.

DATA:FIELDCAT1 TYPE SLIS_T_FIELDCAT_ALV.

CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'

EXPORTING

I_PROGRAM_NAME = SY-REPID

I_INTERNAL_TABNAME = 'ITAB'(this will contain all the fields u want to display)

• I_STRUCTURE_NAME = 'ITAB'

• I_CLIENT_NEVER_DISPLAY = 'X'

I_INCLNAME = SY-REPID

• I_BYPASSING_BUFFER =

• I_BUFFER_ACTIVE =

CHANGING

CT_FIELDCAT = FIELDCAT1.

regards,

bharat.

Hi,

http://www.sap-img.com/fu015.htm

*data definition

tables:
marav. "Table MARA and table MAKT

*---------------------------------------------------------------------*
* Data to be displayed in ALV
* Using the following syntax, REUSE_ALV_FIELDCATALOG_MERGE can auto-
* matically determine the fieldstructure from this source program
Data:
begin of imat occurs 100,
matnr like marav-matnr, "Material number
maktx like marav-maktx, "Material short text
matkl like marav-matkl, "Material group (so you can test to make
                        " intermediate sums)
ntgew like marav-ntgew, "Net weight, numeric field (so you can test to
                        "make sums)
gewei like marav-gewei, "weight unit (just to be complete)
end of imat.

*---------------------------------------------------------------------*
* Other data needed
* field to store report name
data i_repid like sy-repid.
* field to check table length
data i_lines like sy-tabix.

*---------------------------------------------------------------------*
* Data for ALV display
TYPE-POOLS: SLIS.
data int_fcat type SLIS_T_FIELDCAT_ALV.

*---------------------------------------------------------------------*
select-options:
s_matnr for marav-matnr matchcode object MAT1.

*---------------------------------------------------------------------*
start-of-selection.

* read data into table imat
  select * from marav
  into corresponding fields of table imat
  where
  matnr in s_matnr.

* Check if material was found
  clear i_lines.
  describe table imat lines i_lines.
  if i_lines lt 1.
*   Using hardcoded write here for easy upload
    write: /
    'No materials found.'.
    exit.
  endif.

end-of-selection.
*---------------------------------------------------------------------*
*
* Now, we start with ALV
*
*---------------------------------------------------------------------*
*
*
* To use ALV, we need a DDIC-structure or a thing called Fieldcatalogue.
* The fieldcatalouge can be generated by FUNCTION
* 'REUSE_ALV_FIELDCATALOG_MERGE' from an internal table from any
* report source, including this report.
* The only problem one might have is that the report and table names
* need to be in capital letters. (I had it :-( )
*
*
*---------------------------------------------------------------------*

* Store report name
  i_repid = sy-repid.

* Create Fieldcatalogue from internal table
  CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'
       EXPORTING
            I_PROGRAM_NAME         = i_repid
            I_INTERNAL_TABNAME     = 'IMAT'  "capital letters!
            I_INCLNAME             = i_repid
       CHANGING
            CT_FIELDCAT            = int_fcat
       EXCEPTIONS
            INCONSISTENT_INTERFACE = 1
            PROGRAM_ERROR          = 2
            OTHERS                 = 3.
*explanations:
*    I_PROGRAM_NAME is the program which calls this function
*
*    I_INTERNAL_TABNAME is the name of the internal table which you want
*                       to display in ALV
*
*    I_INCLNAME is the ABAP-source where the internal table is defined
*               (DATA....)
*      CT_FIELDCAT contains the Fieldcatalouge that we need later for
*      ALV display


  IF SY-SUBRC <> 0.
    write: /
    'Returncode',
    sy-subrc,
    'from FUNCTION REUSE_ALV_FIELDCATALOG_MERGE'.
  ENDIF.

*This was the fieldcatlogue
*---------------------------------------------------------------------*
*
* And now, we are ready to display our list

* Call for ALV list display
  CALL FUNCTION 'REUSE_ALV_LIST_DISPLAY'
       EXPORTING
*            I_CALLBACK_PROGRAM = 'Z_ALV_SIMPLE_EXAMPLE_WITH_ITAB'
            I_CALLBACK_PROGRAM = i_repid
            IT_FIELDCAT        = int_fcat
            I_SAVE             = 'A'
       TABLES
            T_OUTTAB           = imat
       EXCEPTIONS
            PROGRAM_ERROR      = 1
            OTHERS             = 2.
*
*explanations:
*    I_CALLBACK_PROGRAM is the program which calls this function
*
*    IT_FIELDCAT (just made by REUSE_ALV_FIELDCATALOG_MERGE) contains
*                 now the data definition needed for display
*
*    I_SAVE allows the user to save his own layouts
*
*      T_OUTTAB contains the data to be displayed in ALV


  IF SY-SUBRC <> 0.
    write: /
    'Returncode',
    sy-subrc,
    'from FUNCTION REUSE_ALV_LIST_DISPLAY'.
  ENDIF.

hi

ex:

Please note that structure ZSTOCK is a custom table and iline looks as follow :-

data: iline type table of zstock with header line.

data: gt_fieldcat type slis_t_fieldcat_alv.

perform setup-fieldcatalog using gt_fieldcat[].

form setup-fieldcatalog using fieldcat type slist_fieldcat_alv.

data: ls_fieldcat type slis_fieldcat_alv.

call function 'REUSE_ALV_FIELDCATALOG_MERGE'

exporting

i_internal_tabname = 'ILINE'

i_structure_name = 'ZSTOCK'

changing

ct_fieldcat = _fieldcat.

loop at fieldcat into lsfieldcat.

case ls_fieldcat-fieldname.

when 'DEPT'.

ls_fieldcat-no_out = 'X'.

when 'DESCR'.

ls_fieldcat-no_out = 'X'.

when 'GOOD_PRD'.

ls_fieldcat-do_sum = 'X'.

endcase.

modify fieldcat from lsfieldcat.

endloop.

endform. " FIELDCATALOG

Dear Mallika Rao,

when you are using

CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'

EXPORTING

I_PROGRAM_NAME = SY-REPID

I_INTERNAL_TABNAME = 'ITAB'(this will contain tha data u want to display)

I_STRUCTURE_NAME = 'DATADictionary STRUCTURE' You need to create a Structure in data dictonary(Mandatory) with the same fields what you want to display on report out put.
