After upgraded to 14.6, we found that SD job creation with "Software packages to deploy with custom settings..." the "Activate at" date is reset:
In "Job Container" tab check "No linkage", then on Jobs tab, set the "Deliver at" and "Activate at" dates. Now go back to "Job Container" tab and change to "Batch job execution" and then go back to tab "Jobs" and the "Deliver at" is still updated (OK) but "Activate at" date is reset (NOT OK).
14.6
a bug in version 14.6
A fix is made and the fix will be included in 14.6 CUM1, which has an ETA of release time as May, 2026.
