work status: No status at base member

Hi Folks,

Currently I am working on as BPC 10,1 Classic version below are the details of system.

I have sap all access. even i am owner and manager of the parent member.

Below are the WS setting. for testing purpose i have given access to both.

I am facing problem in Work status. I am not able to change work status of parent member. when i use "include descendant" work status  get changed for base member but not for the time's parent member.I checked backed end tables,WS status getting changed for parent member of owner dimension but not time dimension.

system shows current status of member is none. Whenever i change the WS status every time system show that "The Work Status  was changed to none".

I have checked back end table. look of for me.

Thanks.

Sushant.
