Problem with tran code ME9F

Hi all,

When generating a Purchase Order in tran code ME9F, it is taking like 20 minutes to print the PO. Even our basis team is unable to understand.

One possible cause could be the transaction is reading in a table in which there is no index. Does anyone know in which table it is reading so I can create the index?

Any ohter solution will also be welcome.

Thanks,

Nelmaz
