I'm trying to use " insert into ... select * " to populate a table with PPI and am getting an error saying "Invalid Date Supplied for tablename.columnname" where tablename.columnname is the target table. The source and target table structures are exactly alike, with the same PPI range specified. I'm just trying to copy existing data into a another table for some testing. Will an insert into not work with a PPI table? If not, what's the best way to copy the data? Thanks.
