Hi,

End users were asking some purchase orders were firmed even they didn't know when they firmed those purchase orders.

While I talked with users I realized below.

» When user updates supplier information against planned order in Supplies and Demand table, the planned order was firmed.

» Then those orders were release and craeted purhcase orders.

I want to know this is expected behavior or not.

I suppose supplier update is not firmed. Because it might be caused addition planned order when demand date is changed.
