After upgrading to 15.4 (On-Demand), we ran the PPM health report and noticed that there are errors showing in the time slice section. When hovering over the error icon, it shows a popup stating that the "from date" and "number of periods" must match for all items in that time slice period (daily, weekly, monthly etc.).
CA PPM 15.x and up
This alert in the health report is caused by the there being time slices which have the same slice period, and number of periods, but have different "from" dates.
Edit the timeslices to meet the following requirements:
1. ensured all FROM dates on timeslices are set to a monday
2. ensure that on the monthly ones, they all have the same from date and number of periods
Run the health report again, which should now show the errors/warnings are resolved.
