As per checking of the cause of the error in the web application in the Report by Ticket Owner, the ticket owner dropdown is now displaying a selection because of the query, there is a problem in the query thus it is not returning a ticket owner, modified the query until the ticket owner selection displays, tested the report and as per checking, it is now OK, all the functions are tested in the report and all is OK.
Tested the Report by Business Unit and checked all the functions to see if there are any errors, as per checking, no error is encountered, and all is working.
Continued to check the cause of the error in the Report by Resource, when clicking the search button, the database on the selected filter is not displaying in the UI but when clicked the download, it is displaying, continued to modify as well the Ticket Activity Log report to fix the multi-select dropdown for ticket owners, the value is not changing based on the selected business unit dropdown, but when if the multi-select is not added, it does taking effect, this is still for fixing.
