Did you created a screen?

On that screen did u created a Custom Container?

Did you created an instance for Custom Container?

There will be so many other questions also.

Check these things. Search Forum you will get many helpful documents for the same.

Hi Raj,

We create a screen with a custom control and use that screen for displaying the ALV output.

Please Check the below code, you will understand.

Data Declarations :



DATA : MY_CONTAINER      TYPE REF TO CL_GUI_CUSTOM_CONTAINER,
       GRID              TYPE REF TO CL_GUI_ALV_GRID,
       GT_FCAT           TYPE TABLE OF  LVC_S_FCAT WITH HEADER LINE.
DATA : BEGIN OF GT_VBAK OCCURS 0,
        VBELN   TYPE VBAK-VBELN,
        ERDAT   TYPE VBAK-ERDAT,
       END OF GT_VBAK.

Call the screen



START-OF-SELECTION.

  CALL SCREEN 200.

IN PAI of screen 200*


SET PF-STATUS 'ZMMK_OOPS1'.

  SELECT VBELN
         ERDAT FROM VBAK INTO TABLE GT_VBAK
               UP TO 10 ROWS.


  CREATE OBJECT MY_CONTAINER
    EXPORTING
      CONTAINER_NAME              = 'CC1'
     EXCEPTIONS
      CNTL_ERROR                  = 1
      CNTL_SYSTEM_ERROR           = 2
      CREATE_ERROR                = 3
      LIFETIME_ERROR              = 4
      LIFETIME_DYNPRO_DYNPRO_LINK = 5
      OTHERS                      = 6.


  CREATE OBJECT GRID
    EXPORTING
      I_PARENT          = MY_CONTAINER
     EXCEPTIONS
       ERROR_CNTL_CREATE = 1
      ERROR_CNTL_INIT   = 2
      ERROR_CNTL_LINK   = 3
      ERROR_DP_CREATE   = 4
      OTHERS            = 5.

build field cat


  
  GT_FCAT-FIELDNAME = 'VBELN'.
  GT_FCAT-TABNAME   = 'GT_VBAK'.
  APPEND GT_FCAT.


  GT_FCAT-FIELDNAME = 'VBELN'.
  GT_FCAT-TABNAME = 'GT_VBAK'.
  APPEND GT_FCAT.


CALL METHOD GRID->SET_TABLE_FOR_FIRST_DISPLAY
    CHANGING
      IT_OUTTAB                     = GT_VBAK[]
      IT_FIELDCATALOG               = GT_FCAT[]
    EXCEPTIONS
      INVALID_PARAMETER_COMBINATION = 1
      PROGRAM_ERROR                 = 2
      TOO_MANY_LINES                = 3
      OTHERS                        = 4.

*In PBO of Screen 200.


case sy-ucomm.
when 'back'.
leave program.
endcase.
