Hi,

You have to refresh the display of your ALV grid. You can use CL_SALV_TABLE->REFRESH( ) method if you are using CL_SALV_TABLE.

If you change the settings for your output table, you may need to refresh the display. To do this, use the method REFRESH. To speed up the process, however, you do not absolutely have to rebuild the entire output table. You are able to choose between the following:

SOFT

This is the quickest way to refresh the display. You use it, for example, when you are only changing the sequence or selection of columns, but the number and sequence of the rows displayed remains the same.

FULL

You use this variant when you have also changed the metadata, forexample, when you have applied different sorting or another filter.

Parameters

S_STABLE

Optional

Rows and/or column position stay the same; Type LVC_S_STBL

REFRESH_MODE

Optional

Depth of refresh; Type SALV_DE_CONSTANT (IF_SALV_C_REFRESH)

Refresh Constant Value

No refresh NONE 0

Minimal refresh SOFT 1

Complete refresh FULL 2

Thanks and Regards,

    EXCEPTIONS
      FINISHED = 1
      OTHERS   = 2.
  IF SY-SUBRC <> 0.
    MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
               WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.

Hi,

1. Try "Free".

    IF DATA_GRID IS NOT INITIAL.
      CALL METHOD DATA_GRID->free
        EXCEPTIONS cntl_error        = 1
                   cntl_system_error = 2.
      FREE DATA_GRID. "** May be you forgot this statement**"
    ENDIF.

2. If "Free" still doesn't work, Try "REFRESH".

  IF DATA_GRID IS NOT INITIAL.
    REFRESH <dyn_table>.
    CALL METHOD DATA_GRID->refresh_table_display.
  ENDIF.

Regards,
