Editable alv

Former Member — Tue, 04 Mar 2008 13:46:29 GMT

Hi,

I have an ALV in which I am inserting a new row.

once new row is inserted , a value is given in the first cell. once the value is filled , rest of cells in that row should be grayed out i.e user can not enter values in the rest of cells.

This is working fine.

But when I have inserted one more row , the previous row is now turning into editable.

Could you please suggest me.

Regards,

Satya

set a variable g_flag = 'X', at the time u r filling editable row

and put alogic to make that new row greyed as it was done earlier for other rows.

I think problem is :

when u add on button to insert new row

first time : all the records which are greyed coming from database table into internal table.

but second time: logic may be differernt, thats why it is not making previous added row greyed.

I hope u understand bit,

otherwise pls explain ur problem in detail.

Dont forget to rewards points.

hi,

try this code for one field editable or for reference pls open object navigator (se80 , and refer BCALV_EDIT_02 )based on one condition only those rows are in edit mode , rest of the rows are in disable mode, just copy and paste the code in se38 and run

REPORT ZEDIT_ONE_CELL_OOPS.

*Essential steps (search for '§')

~~~~~~~~~~~~~~~
1.Extend your output table for a field, e.g., CELLTAB, that holds
information about the edit status of each cell for the
corresponding row (the table type is SORTED!).
2.After selecting data, set edit status for each row in a loop
according to field SEATSMAX.
2a.Use attribute CL_GUI_ALV_GRID=>MC_STYLE_ENABLED to set a cell
to status "editable".
2b.Use attribute CL_GUI_ALV_GRID=>MC_STYLE_DISABLED to set a cell
to status "non-editable".
2c.Copy your celltab to the celltab of the current row of gt_outtab.
3.Provide the fieldname of the celltab field by using field
STYLEFNAME of the layout structure.
