ALV Grid select rows

Former Member — Tue, 07 Aug 2007 14:51:07 GMT

Hi All,

I have a requirement.

In the ALV grid, IF I select a row and click the Change button... I have to prompt a customized screen which display the selected row values.

For example,

the screen should display as follows

Field1 12345

Field2 XXXX

Field3 hhhh

How to get the selected row values and transfer it to the customized screen.

And If i change any of the values in the screen and click the save button, the values should be updated in the ALV grid.

How to do this... kindly help...

Thanks,

Jaffer Ali.S

HI,

Create a Screen to display a record in edit mode.. in SE51 for the program.

in ALV grid.. use USER_COMMAND and give the name of the subroutine for the interactive functionality..

when 'CHNG'. " remember you will have the complete selected line in the subroutine parameters when dealing with ALV..

&----

*& Form USER_COMMAND

&----

form user_command using p_ucomm like sy-ucomm

p_selfield type slis_selfield.

data : l_index like sy-index,

l_refbn like cooi-refbn.

<b> l_index = p_selfield-tabindex. " holds the selected table index</b>

clear l_refbn.

case p_ucomm.

when 'CHG'.

clear l_refbn.

read table it_outtab index l_index.

if sy-subrc eq 0.

move-corresponding fileds to your screen fields.

call screen <Your screen number>

else.

message e999 with text-014.

endif.

endcase.

endif.

And in the PAI of your screen say modity interntable with this detaisl..

Thanks

Mahesh

Its a little different using the class, First you need to set the selection module before calling the SET_TABLE_FOR_FIRST_DISPLAY method.

data: LAYOUT TYPE LVC_S_LAYO,

LAYOUT-SEL_MODE = 'D'.

CALL METHOD ALV_GRID->SET_TABLE_FOR_FIRST_DISPLAY

EXPORTING

IS_LAYOUT = LAYOUT

CHANGING

IT_OUTTAB = IALV[]

IT_FIELDCATALOG = FIELDCAT[].

So this will give you the selection box in the ALV output, then you use the method GET_SELECTED_ROWS to determine what rows the user has selected.

DATA: INDEX_ROWS TYPE LVC_T_ROW,

INDEX LIKE LINE OF INDEX_ROWS.

CLEAR INDEX_ROWS. REFRESH INDEX_ROWS.

CALL METHOD ALV_GRID->GET_SELECTED_ROWS

IMPORTING

ET_INDEX_ROWS = INDEX_ROWS.

Do something with those selected rows here

LOOP AT INDEX_ROWS INTO INDEX.

Use the index to read the specific line of ALV which is selected

READ TABLE IALV INDEX INDEX-INDEX.

IF SY-SUBRC = 0.

Now do what ever you need to with the selected line

ENDIF.

ENDLOOP.
