Production Volume in account based COPA

Hi,

Would like to know the setting in account based COPA

on how to configure the production volume at the time of production order confirmation.

Have ticked on the "record

qty" for manufacturing output cost element but there is no PA document generated though the Costing document clearly recorded

the quantity. Have checked on actual flow of FI/MM document with tick on "Profit Segment", there is no PA document in

account-based COPA too.

For costing-based, the setting is successfully done via T-code KEI1.

Please help.
