It could be relevant to verify what is the content of the db in reference to the notifications.
To do that, a query can be run on the ‘not_log’ table, the table containing all the notifications.
1. via SQLServer Management studio, find the persid of the incident being evaluated:
select persid from call_req where ref_num = '<incident_number>'
where <incident number> is the reference number (ref_num) of the incident displayed in Service Desk.
2. using the persid found in step 1:
select * from not_log where cntxt_obj = '<persid found in previous search>'
In this way we get all the notifications, related to the specific incident identified by ‘<incident_number>’, stored in the database.
The result can then be compared to what is displayed in Notification History.
