Error while changing status of WBS from CLSD to TECO

Hi Experts,

I am facing an issue while changing the status of WBS from CLSD to TECO. After TECO while saving I am getting following error.

Please find the attched error screen for reference.

While removing the investment profile of the WBS element I get following error “Settlement
account assignment is not allowed”

AUC number exists for all WBS elements with nil quantity.

Thanks in advance.

Regards,

Sudhindra
