repair full load - is basically used when you need to add (older) records to an existing delta flow
in case of Logistics Workbench extractors, the data is read from the setup tables, for all other extractors you need to specify selection criteria
now it seems COPA acts a bit differently (just double checked in a system)... not sure yet/anymore how/why... I'll investigate
what I meant was: are you sure the historic data is still in the source system (when archived, it's usually deleted from the source system and stored elsewhere)
but that's probably not the case
