Problem with Maintenance View

Hi All,

I have created a maintenance view on two table EKKO and EKPO. All the key fields are included properly in the view fields, EBELN from EKKO and EBELP from EKPO. But now when i maintain this view via Transaction SM30 data is getting saved only in table EKKO or say only in header table. It is not reflecting in Item table. Will a maintenance view really allow me to enter data into two tables simultaneously? If yes then why i am not able to save data into Item table. I have searched forum but did not get proper answer.

Please help me .

Regards,
