SAP allows to book actual cost if WBS system status is CRTD

Hi Experts,

We have a project and WBS elements having system status CRTD. So far it was our impression that if WBS status is CRTD, system will not allow to book actual cost in WBS. But now we found a WBS having actual cost in status CRTD, the cost is being booked through FI transaction by Finance department.

Thanks
