What is the best way for BW refresh Via TDMS

Hi,

BW is running on HANA , BW QA system needs to be refreshed from production data via TDMS RFC refresh method. If process chains/ delta queue's are not stopped during data capture stage it will create problems with dumps in both in bound and out bound Queues in QA.

Kindly let me know ,

Do we have to stop process chains ? or any other way out without stopping

Does TDMS file based refresh provide any solution to this?

regards

Vinay
