Order is locked by user while filling setup table

Hi Experts,

Yesterday while i am filling setup table for 2LIS_DM_VAITM (DBM Sales) data source it got cancelled.

It showed that " Order xxxxxx is locked by user".

Because we have DSO concept in our CUBE, we didn't lock users.

But then the basis checked the users and removed from the system.

But still after removing the users, when we do the setup filling it still gets cancelled showing the same error.

Please help on this. Now i am stuck in filling setup section.

Thanks,

Thilini
