Accessing all the line items of Purchase requisition(ME51N)

Hi All,

Is there any way to access all the line items of a purchase requisition(ME51N) at a time?  I Implemented a BADI ‘ME_PROCESS_REQ_CUST’ and check all the interfaces like PROCESS_ITEM, CHECK, POST etc and found these interfaces only triggers for one line item which is currently being processed. Can anyone suggest.

Regards,

Jitendra
