Hi Chetan,

The EKPO query is perfectly ok as you are using PO no to get PO line items.

In the EKBO query you can add MBLNR also as your driver table is t_MSEG - but still it looks quite ok.

Put the initial check for the driver table in both these queries.

So where are you getting the performance problem ? In production or Quality ? It might be the case that database has too much data and it's time to archive some data so that the system runs better. Just check the no of entries in all these table.

About BKPF access - please see if yiu can use other tables like BSIS, BSID etc
