Consider Service Item for descriptive global purchase processing

Hi Team,

The " Consider service item for descriptive global purchase order processing " option is ticked in our supply chain financial orchestration system options page. This was a new setting in 22D and this defaults account codes based on the service items that we have.
The issue with this is that only one service item can be setup at a time so any SCFO transactions with a different UOM will fail and we have to recover them regularly, by changing the service item.
Advice needed on what other set up is necessary if we untick 'consider service items' option
