Validation on ALV screen

[Former Member]

Hi All,

Iam using ALV grid display in my program.

I have two columns say A and B botha rre numeric.

A can be modified where as B cannot.

I will enter some value in A say 5 where as B is 3.

Then we will save that layout ,while saving i want apopup saying you cant enter more than B.

Is it possible to know which row he ahs changed.

is that possible in REUSE_ALV_GRID_DISPLAY.

With Regards,

you can compare the data, in SAVE sy-ucomm, and then give pop up based on your condition...

<b>selfield TYPE slis_selfield.</b>

Using SELFIELD you can find index and fieldname also,

but your case use index and read record then give pop up according to your requirement

gd_repid LIKE sy-repid, "Exists
ref_grid TYPE REF TO cl_gui_alv_grid. "new

then insert the following code in your USER_COMMAND routine...

FORM user_command USING r_ucomm LIKE sy-ucomm
rs_selfield TYPE slis_selfield.

IF ref_grid IS INITIAL.
CALL FUNCTION 'GET_GLOBALS_FROM_SLVC_FULLSCR'
IMPORTING
* ET_EXCLUDING =
* E_FLG_NO_HTML =
* E_REPID =
e_grid = ref_grid
* ES_LAYOUT_KKBLO =
.
ENDIF.

IF NOT ref_grid IS INITIAL.
CALL METHOD ref_grid->check_changed_data
* IMPORTING
* E_VALID =
* CHANGING
* C_REFRESH = 'X'
.
ENDIF.

Note try to take backup before calling FM, and then using that you can compare the data,

Hi kiran,

when 'SAVE'

Data ref1 type ref to cl_gui_alv_grid.

CALL FUNCTION 'GET_GLOBALS_FROM_SLVC_FULLSCR'

IMPORTING

E_GRID = ref1.

call method ref1->check_changed_data

Loop at itab.

if itab-cola Gt colb.

use FM for POP UP

endif.

endloop.

[Former Member]

When 'SAVE'

CALL METHOD W_GRID->CHECK_CHANGED_DATA

IMPORTING

E_VALID = L_VALID.

*l_valid will return X if any data is changed on grid

IF L_VALID = 'X'.

loop at itab.

if col A GT col B.

use the FM to get popup(will give u if needed).

endif.

endloop.

endif.
