"CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'"

but i dont know how to give name dynamically....i am new to this ...so could you please help me out....

if there is any other way to do so . please lemme know...

*For Function module ALV (report)

 DATA: it_fieldcat  TYPE slis_t_fieldcat_alv,
        wa_fieldcat   LIKE LINE OF it_fieldcat.
 DATA: table LIKE  DD02L-TABNAME.

 Populate the table nam here.
table = 'MARA'.
  CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'
    EXPORTING
      i_structure_name       = table
    CHANGING
      ct_fieldcat            = it_fieldcat
    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.

U have to pass the value to table so that it will create the structure.

reward if u find helpful.

YOu can use the fm GET_COMPONENT_LIST to get the structure of the internal table at the run time.

You can also use the REUSE_ALV_FIELDCATALOG_MERGE fm.
