Business function:LOG_MM_SIT activation for standard OAF functionality

Hello Experts,

We are implementing standard Origin acceptance flag functionality in external procurement from vendor using PO.(mvt types 107,109)

We have scenario to receive valuated project stock (acct.assigned category=Q)through OAF PO.

This requires activation of business function LOG_MM_SIT.

Is anyone implemented standard OAF functionality with business function activation?

Could you please share risk in activation and additional processes/changes that it adds to system?

Thanks in advance for your valuable feedback.

Best Regards,

Shyam
