EPM 10 report Error (BPC on HANA)

When I m trying to execute EPM 10 report, somtimes the system throws the following error.

"The execution of the report failed " - UJHANA_SQE_EXCEPTION_007

Run SQE HANA Query fail

Attached screen shot of the same.

The error seems to get resolved when i try to process the dimension used in the report and Run UJA_REF_DIM_CACHE ,but it reappears again randomly .

Would like to understand the root cause of the issue if any along with the troubleshooting steps.

Thanks in advance for your help.
