    To my knowledge I have never hit the wall, but you must realize that the more records, the more time it will take to render the ALV grid as well as scroll thru it, sort it, subtotal it, filter it, etc. You should try to keep the size to a manageable size, also, what user will scroll thru thousands of rows in an ALV Grid? Right?

    How many lines are we talking about? 10,000? ALV grid will display this many, but performance may be an issue, and more so as the size goes up.

    Hi,

    As per the SAP documentation You can have any number of lines..

    The SAP List Viewer can be used to view both single-level lists and multilevel sequential lists.

    Single-level lists contain any number of lines that have no hierarchical relationship to each

    other.

    Multilevel sequential lists consist of any number of lines that have two hierarchical levels.

    Multilevel lists have header rows and item rows; the item rows are subordinate to the header

    rows. For each header row there can be any number of subordinate item rows.

    Thanks,

      Yes, any number of rows, you limit will be the the amount of memory that you internal table consumes. You will be limited by the global system setting, in my system I believe that it is about 2gb of memory. Yes, ALV list display can be ran in background. If you are using the REUSE function module, it will be converted to an ALV list display automatically, if you are using the class based ALV(CL_GUI_ALV_GRID), you must do addtional coding for it to be handled correctly in the background.

    Yes...Alv can be run in the background if you are using the FM ...Otherwise for GRID as mentioned by Rich..You have to do additional coding..

      No need to change the gui status, If you simply want to exclude the excel button, you can do this. Check code in <b>BOLD</b>.

      
report zrich_0003 .



* Global ALV Data Declarations
type-pools: slis.

* Internal Tables
data: begin of ialv occurs 0,
      test1(10) type c,
      test2(10) type c,
      end of ialv.

data: fieldcat  type slis_t_fieldcat_alv.

start-of-selection.

  perform get_data.
  perform call_alv.

*********************************************************************
*      Form  GET_DATA
*********************************************************************
form get_data.

  ialv-test1 = 'ABC'.
  ialv-test2 = 'DEF'.
  append ialv.

  ialv-test1 = 'GHI'.
  ialv-test2 = 'JKL'.
  append ialv.


  ialv-test1 = '123'.
  ialv-test2 = '456'.
  append ialv.


endform.                    "GET_DATA

************************************************************************

*  CALL_ALV
************************************************************************

form call_alv.

<b>  data: excluding type  slis_t_extab.
  data: xexcluding like line of excluding.


  xexcluding-fcode = '&VEXCEL'.
  append xexcluding to excluding.</b>

  perform build_field_catalog.


* Call ABAP List Viewer (ALV)
  call function 'REUSE_ALV_GRID_DISPLAY'
    exporting
<b>      it_excluding = excluding</b>
      it_fieldcat  = fieldcat
    tables
      t_outtab     = ialv.

endform.                    "CALL_ALV

************************************************************************

* BUILD_FIELD_CATALOG
************************************************************************

form build_field_catalog.


  clear: fieldcat. refresh: fieldcat.

  data: tmp_fc type slis_fieldcat_alv.

  tmp_fc-reptext_ddic = 'Test1'.
  tmp_fc-fieldname    = 'TEST1'.
  tmp_fc-tabname      = 'IALV'.
  tmp_fc-outputlen    = '10'.
  append tmp_fc to fieldcat.

  tmp_fc-reptext_ddic = 'Test2'.
  tmp_fc-fieldname    = 'TEST2'.
  tmp_fc-tabname      = 'IALV'.
  tmp_fc-outputlen    = '10'.
  append tmp_fc to fieldcat.


endform.                    "BUILD_FIELD_CATALOG

    Hi,

    Yes..You can remove the buttons..You can copy existing Standard SAP GUI status (STANDARD)and create a new one

    and remove the buttons...

    In the parameter I_CALLBACK_PF_STATUS_SET of the FM..GIve a form name..

    IN the form use command SET PF-STATUS to call the new one that you created..

    Thanks,
