BI Publisher Report and Data Model Last Modified Date and Time
We use BIP 11.1.1.6.2, integrated with OBIEE.
I've noticed that on the Sunday of every week in both our PROD and DEV instances the Last Modified date and time for all of our reports and data models is updated to the same date and time (same date and time within each instance, but different per instance). We do weekly shutdowns of our PROD and DEV environments and I'm wondering if there is a process that touches the files and changes the last modified date?
Could anyone tell me what would be changing the last modified date on a weekly basis, and why it would be changing the date? We'll need to be able to explain this to our auditors.
