This technical article documents a design change in UIM 20.4 related to the columns shown when in the Group tab -> View Alarms.
Steps to replicate this behaviour:
1. Access the OC -> Select the Groups tab -> Select a Group -> Select the Alarm View button -> Select the 3 dots for further options.
2. The edit columns is not available to modify:
Release : 20.4
Component : UIM OPERATOR CONSOLE - ALARM VIEWER
Working as designed as of 20.4CU1, Enhanced in 20.4 CU3 and later
The enhancements made to remove some options from the Group View (irrelevant actions are removed from the 3 dots menu) as seen below.
It is expected that these actions are removed. They are available in the Alarm Viewer and changes made to those settings will apply to all other alarm views. This design ensures consistency across views.
