Unable to remove DAP from team

Dear Experts,

I am working on SAP BPC 10.1 NW (Classic) version.

I am trying to remove DAP from a team.

BPC allows me to remove the DAP from team but when I try to save it,

following error is displayed.

I have tried this using a user ID having all tasks authorization for BPC and also using an ID having SAP_ALL.

Regards,

Amit
