How to find out when a non-Production database got refreshed from a copy of Production in PeopleSoft. Is there a PeopleSoft/Oracle table (or tables) that have the date and time of the refresh? I have checked the PSPRCSRQST and PSPRCSQUE tables in PeopleSoft non-Prod database based on the Process Instance (PRCSINSTANCE). But how to know which was the last Process Instance in the Production database that is same as in the non_Prod database? Is there any other way to find the last refresh date of non-Prod database refreshed from Prod database?
