Historian Data Validation Signoff Missing Before Final Payment Email Template

Use this page when final payment is delayed because the buyer says the historian data validation signoff, historian acceptance report, or historical-data approval is still missing. This differs from a SCADA display or reporting page because the missing deliverable is the confirmation that data is being stored correctly, tagged correctly, and retained as agreed. The commercial problem is that the site may already be operating, but the payer is still holding payment because the long-term data record has not been signed off. Your email should ask whether the historian validation is the only blocker left, whether the latest validation sample has already been submitted, what tag, archive, or retention issue is still unresolved, and whether payment will be released once the validation is approved. The outcome you want is to isolate the delay to one exact historian closeout item instead of general comments about incomplete analytics or reporting.
