Hi,
Need help below is my Requirement on Incident form
Need to create Business rule When any user tries to add parent incident number on any incident form it should check the parent already has any other child incident
if No update the parent incident number to the incident form
if Yes needs to pop up message "the selected parent incident already has child"
like wise if user tries to add child incident to the incident form it should check the child has already parent or not
If yes it should give error message the selected child incident already has parent
If No it should allow
In simple each parent will have one child
Thanks in advance
