We have exported defects logs from xls to QC. We have started using QC for all on going projects. So normal process we want to follow is that everyday our testing team will send updated defect logs with some new defects and updates to existing defects and then we will export the delta values in excel to QC.
There are some issues with uploaded delta values. If we assume that there are changes in status for 2 existing defects then after exporting to QC, it should update status of already uploaded defect. But QC is adding 2 new defects instead of updating status of existing defects.
