Thank you for discussing and posting relvant information on this forum section.
Today I again come up with new question :)
What exactly a difference between GetPIArchieveData with 1 value and GetPISnapshotData?
In user guide it is mentioned that "GetPIArchieveData with Start Date = *, End = *, Compressed with Outside" is similar to GetPISnapshotData. If this is so then why we need a GetPISnapshotData operation in the service? Also, in terms of performance and data retreival which is best?
