Changing Actual Start and Finish Date after WBS is set to TECO

Hi,

We would need the Actual start & Finish Dates of the WBS element to be available for editing even if the WBS element has been set to TECO. Currently in the system if the WBS element is already set to status TECO, then update is not possible for the actual start and atual finish date fields.

Could you advise if there is any way to do that? It seems to be a SAP standard behaviour.

Thanks!
