As reported by the RSCI team the Nav Transaction from July to November 11, 2020, was reverted again. Asked Nicay if there are ways to verify if it was deleted/remove in the database or this is just a glitch in the system. Nicay of PASI advised me to check the logs in the database but as per checking it only shows the activities in the SQL Server. Tried the 2nd option of Nicay to check the Change Log in NAV 2009, search the web on how to do this but as per checking it only shows the changes made per account not sure if it's only for the admin side or per machine only. I will continue my checking tomorrow on this.
