There is an OOB calculation on format control IM.update.incident which initializes resolved.time, resolved.by NULL on initialization of format.
Steps to reproduce:
1. Resolve an Incident
2. Save the Incident
3. Exit and again search the Incident
4. Resolve time is NULL
If user saves the record it make the resolve time NULL.
Calculation:resolved.by in $file=NULL;resolved.group in $file=NULL;resolved.time in $file=NULL;adj.resolution.by in $file=NULL;adj.resolution.time in $file=NULL
Go to trigger and set a trigger –>add.resolution.infomation
Tigger Type –>3 – Before Update
Application –>leave blank
if(record.problem_status==’Resolved’ && oldrecord.problem_status !=record.problem_status)
