In ALV Report ,a field to allow the user EDIT/CHANGE

Hi Guys,

My requirement is

in the ALV Grid display iam having 10 fields.5th field should be allow the user EDIT/CHANGE mode.

what ever he enters the value the same should be updated to an custom table.

EX.

o/p:

0001 0002 0003 0004 0005 0006 0007 0008 0009 0010

Now the user changed the value 0005 to 0011.

0001 0002 0003 0004 0011 0006 0007 0008 0009 0010

now 0011 should be updated in custom table.

to do this process please suggest a best way for coding.

thanks in advance.

Sunil.
