Query regarding ALV

Former Member — Tue, 24 Jul 2007 07:05:40 GMT

Hi all,

Please clarify this query of mine in ALV.

***Code:**

data : itab_data1 like standard table of zdetails1.

data: repid type syrepid.

data : fieldcat type slis_t_fieldcat_alv.

repid = sy-repid.

call function 'REUSE_ALV_FIELDCATALOG_MERGE'

exporting

i_program_name = repid

i_internal_tabname = 'itab_data1'

i_bypassing_buffer = 'X'

changing

ct_fieldcat = fieldcat

EXCEPTIONS

INCONSISTENT_INTERFACE = 1

PROGRAM_ERROR = 2

OTHERS = 3.

After the execution of the Function Module the fieldcat does not contain any rows .

Kindly explain me why the fieldcat does not contain any rows.

Please reply as fast as possible.

Regards,

Vijay

Use this code instead.

call function 'REUSE_ALV_FIELDCATALOG_MERGE'
exporting
I_STRUCTURE_NAME = 'ZDETAILS1'
i_bypassing_buffer = 'X'
changing
ct_fieldcat = fieldcat
EXCEPTIONS
INCONSISTENT_INTERFACE = 1
PROGRAM_ERROR = 2
OTHERS = 3.

Please mark points if the solution was useful.

Manoj

Hi,

See how SAP uses:-

--- merge fieldcat from ddic structure ---

CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'

EXPORTING

i_program_name = con_self

I_INTERNAL_TABNAME = PD_TABNAME_FIELDCAT

i_structure_name = pd_strucname_ddic

I_INCLNAME = LC_INCLUDENAME

CHANGING

ct_fieldcat = lt_fieldcat

EXCEPTIONS

OTHERS = 1.

Reward if useful!

Hi Balasubramanian,

In the FM you need to pass the parameter

I_STRUCTURENAME with the ZStructure that you have created in the data dictionary. Then it will work.

Reward if answer is informatory.

Best Regards,

Ram.

Try like thi s

data : itab_data1 like standard table of zdetails1.
data: repid type syrepid.
data : fieldcat type slis_t_fieldcat_alv.


call function 'REUSE_ALV_FIELDCATALOG_MERGE'
exporting
i_program_name = sy_repid
i_internal_tabname = 'ITAB_DATA1'
i_bypassing_buffer = 'X'
changing
ct_fieldcat = fieldcat
EXCEPTIONS
INCONSISTENT_INTERFACE = 1
PROGRAM_ERROR = 2
OTHERS = 3.

check this sample one

 type-pools : slis.
 
data : begin of it_toto occurs 0 ,
         matnr type matnr ,
         maktx type maktx ,
       end   of it_toto ,
 
       it_fieldcatalog  type slis_t_fieldcat_alv.
 
 
 
 
CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'
  EXPORTING
    I_PROGRAM_NAME               = sy-repid
    I_INTERNAL_TABNAME           = 'IT_TOTO'
*   I_STRUCTURE_NAME             =
*   I_CLIENT_NEVER_DISPLAY       = 'X'
*   I_INCLNAME                   =
    I_BYPASSING_BUFFER           = 'X'
*    I_BUFFER_ACTIVE              =
  CHANGING
    ct_fieldcat                  = it_fieldcatalog.
* 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 Bala,

Along with the I_STRUCTURE_NAME, also pass the I_INCLNAME = SY-REPID.
