Hi Dharani,

The following program demonstrates how to make individual fields of an ALV grid editable (NetPR greater than 10).

Changes required from a basic ALV grid include adding a new field to ALV grid data table(it_ekko), Populating this

field with style attribute and adding an entry to layout control table. Also from the previous examples used on

this website you will also need to change the data type of the fieldcatalog, the layout and use a different function

module for displaying the report.

hi dharani,

go to se41 transaction,

give the program name as SAPLSALV,and status as 'standard'

and copy it to a diffrent status with your z-program

then do the necessary changes whatever u want,

then go to your z-program,

where in ALV function module u have to specify the

IS_LAYOUT parameter
