Problem

The smart client and thick client date selector is not working properly or as expected. It is affecting anyone trying to filter the date column as the system is not accepting the value selected and therefore can not filter on reports or configuration.

This behavior occurs with short date format in thick and thin client, only when you set language other than English (United States) in APM configuration.

Solution/Workaround:

1. Set enterprise to long date format. See APM help for more information: Changing User Interface (UI) Settings



OR

2. Set Thick and smart client language to English (United States) in APM configuration. See APM help for more information Changing the Language for the APM Server
