How to unlock ODS object

Hi,

When I try to activate data in ODS object(by activating requests) the following message is displayed:

"Activate terminated, because InfoCube/ODS object MYODS could not be locked".

As I understand the ODS object is locked by another process, but how to determine this process and unlock the ODS object ?

Please help (dont worry, points will be provided 😊 )

Thank in advance
