Hi.
go to PE02 and give you PCR and click on change button.
now type "D"in the last digit in line which you want to delete. and press enter key. then that line will be deleted. after that save it.
have a look my screen shot. where im deleteding line 0070.
once you type D . press enter key. then it will be deleted.
now you can see that line 0070 has been deleted and line 0080 becom as line 0070.
like wise you can use "I" to insert line "C" for copy.
Regards,
Dinesh
