OK, so please check your M187 posting control setup in Accounting Rules. Perhaps project code part is not needed there at all.
Please as well check on which account (code part A) M187 is directed and if this account is included in project follow-up. If project is needed, M187 account should be liabilities or assets account and excluded from project-follow-up (without need for project activity sequence)
