Hi,
Basically these kind errors will get when you are loading data into cube or DSO, at the same time when you are reading data from loading cube are DSO it occur same error and also.
These kind of error occur when you acitvate the data in DSO, if data is updating to some other targets.
So my advise is we need to wait up to Current run finish.
Please let me know if you need any more info.
If you are ok with my message please give some points.
Regards,
Satya.
