Dear Pawan
Remove Old field value for all below scenarios, & maintain below values as below:
Create user:
Field_name =USRID
New FIELD Value = is not initial
parent type = 105
sub type = 0001
Change user
Field_name =PLANS
New FIELD Value = is not initial & exclude 999999999
parent type = 0001
sub type = no value
Terminate
Field_name =MASSN
New FIELD Value = check the HR trigger log for exact value by terminating a user which can be done by many reason in PA40.
parent type = 0000
sub type = no value
Let me know if you have any queries.
