Is it possible to insert an original record in the past for a tag?

In the context of the AVEVA Historian Server and data integrity, it is crucial to understand how historical data management works. The process of inserting an original record in the past for a tag essentially implies altering the historical dataset, which could compromise the reliability and authenticity of the information.

In general, once data has been recorded into the historian database, it is treated as a historical reference. Allowing retroactive insertions could lead to discrepancies and inaccuracies in reports or analysis, as the original chronological sequence of data points would be disrupted. Therefore, it adheres to best practices within data management and preservation principles to prevent any such actions once the data is committed.

While there may be certain configurations or specific scenarios in which data correction or adjustments could be made under strict guidelines, the fundamental principle remains that original records should not be inserted retroactively to maintain the integrity of historical data records. This is why the answer is recognized as false; attempts to record data in the past could undermine the core purpose of a historian which is to provide a reliable and verifiable record of historical data over time.
