Since upgrading to UIM 20.4 (from 20.3), when recalculating Daily SLAs in order to create historic data, only 30 entries of periods are offered.
When this is a daily SLA, it is possible to get historic data only 30 days back (FIXED REPORT)
Using "custom report" and selecting calculate historic data does not change the result of the "History" report either.
In UIM 20.3.x, when recalculating daily SLAs it was possible to select daily periods that went far behind the current limit which seems to be of 30 Days.
The issue is reproduced inhouse on UIM 20.4CU7/CU6
