Revenue Business Unit preference isn't applied during SO Entry
While entering SO I need Revenue BU another than B/P on the SO Header.
Revenue BU preference setup is done as described in Doc 1607575.1
But when I enter SO, the Revenue BU remains the same as B/P on the header.
What else (not mentioned in Doc 1607575.1) can affect Revenue BU in P42101 (P4210) or Revenue BU preference processing?
