Difference between the 2 FM's

Former Member — Wed, 09 May 2007 09:00:10 GMT

Hi experts can anyone please tell me the difference between the 2 function modules:

REUSE_ALV_GRID_DISPLAY and REUSE_ALV_GRID_DISPLAY_LVC . I have seen in the coding for editable ALV that they have made use of the former FM rather than the regular REUSE_ALV_GRID_DISPLAY.

( Source: <a href="http://www.sapdevelopment.co.uk/reporting/alv/alvgrid_editable.htm">Editable ALV from sapdevelopment.co.uk</a> ) So can anyone explain as to whether its actually possible to code the editable ALV using the REUSE_ALV_GRID_DISPLAY FM or not. Thanks

'REUSE_ALV_GRID_DISPLAY' is for the SLIS type pool.

'REUSE_ALV_GRID_DISPLAY_LVC' is for the LVC type pool which of course has a better functionality.

1) Common in display result

REUSE_ALV_GRID_DISPLAY_LVC and REUSE_ALV_GRID_DISPLAY have similar display view

2) Common in usage

REUSE_ALV_LIST_DISPLAY and REUSE_ALV_GRID_DISPLAY have very similar parameters for

function call (types from slis)

one rarely use fm REUSE_ALV_GRID_DISPLAY_LVC as class cl_gui_alv_grid provides more

power and functionality.

REUSE_ALV_GRID_DISPLAY uses SLIS Type group

and

REUSE_ALV_GRID_DISPLAY_LVC uses LVC_.. Structures

And coming to your second question, You can edit the fields using REUSE_ALV_GRID_DISPLAY but you cannot disable the editable fields

So you cannot write the same code using REUSE_ALV_GRID_DISPLAY

better to use REUSE_ALV_GRID_DISPLAY_LVC or OOPS ALV

Hi Navjot & chandrasekhar,

Thanks for your replies. I do still have 1 small doubt. In the example at :

http://www.sapdevelopment.co.uk/reporting/alv/alvgrid_editable.htm

he had declared the SLIS type-pool eventhough he was making use of the REUSE_ALV_GRID_DISPLAY_LVC FM. Could you please say as to why he had to declare the SLIS type pool even for this FM. Sorry am new to ALV's
