TABLE ILLEGAL STATEMENT error with MODIFY command
i want you to inform me about table illegal statement error. The error occurs when i use modify as below.
loop at itab.
where xxx eq itab-xxxx.
i know that i have to give the sy-tabix as INDEX parameter to the modify command. but i want to know why i have to do this?
cause when i debug, i follow the sy-tabix field and it have not a change in select endselect.
may the reason of the error about cursor in select and cursor effects modify command?
