Not Able to backfill data using OPC-to-PI HDA interface

Hi Everyone,


We are trying to backfill a missed history data from an OPC server to our PI server using OPC-PI interface. However, in the middle of the backfilling process we are receiving some error like this "Bad status in OPC HDA call. Scan class1 - The Operation failed". We see that the history recovery completes very fast and only a subset of tags have the backfilled data in the PI server. (Kindly refer the screenshot)


Also, I have verified that the real-time data streaming from the same source is fine and the status of the connection through Matrikon OPC Tunneller is running fine.
