hi,
thanks for all the responses.
1. ok, i will define settlement rule (in this case, client requirement wants AuC)
2. settlement rule is NOT always required to settle. for example, with method 13, "WIP at Actual Costs" we are also using, after RA, we run settlement and even if there is no settlement rule, it will settle to the balance sheet account maintained in OKG8.
good day,
