I have followed this guide to delete some records from our PI Data Archive: https://techsupport.osisoft.com/Troubleshooting/KB/2920OSI8
However, I keep getting these error messages: Piconfig Err> Error reading record from table... Rec: <Specified Tagname>
[-15003] Generic Requested Item Not Found
I have checked that the tag actually exists, and I have checked for any permission issues. piconfig logs in as piadmin according to the PI message log. PI Data archive version is 2017 R2 (3.4.1415.1188)
Any ideas what I could be doing wrong?
