I don't know very much about PI Archive or PI SDK. I tried to figure out my problem by checking previously asked questions but didn't find anybody who seems to encounter my problem.
I can't write any data before the timestamp when the PI Archive was created. Wether by writing C# code or directly typing the value in the PI Explorer Editor, in the past, the value is not registered and I am not getting any error message.
My question is simple: Is it possible to write values before PI Archive creation date ? And does it involve to configure something on the server?
