Performance VA* and VF*

Hello,

I have a performance problem with transactions VA* and VF * with the transaction VA02 for example, an order of about 10 items to enter each have to wait about 3 minutes. By analyzing the transaction SE30 I see that as long to perform xkomv_bewerten PRICING_BUILD_XKOMV function.

Does anyone have a clue? The price is great, this would be the reason for the delay?

Thank you!
