Error in People application while trying to update Supervisor field on Person records.
The error is thrown while trying to save the record:
BMXAA4214E - An unknown error has occurred.
Please contact your system administrator for assistance.
Gather the logs from the <HOME> directory and determine where and why the error is thrown.
Resolving the problem:
1. Run the query below against the database to try to find a Person being the Supervisor of itself:
SELECT PERSONID, SUPERVISOR FROM PERSON WHERE PERSONID = SUPERVISOR;
2. Run the query below against the database to try to find a Person being a Supervisor of a Person who is the Supervisor of the original Person.
SELECT PERSONID, SUPERVISOR FROM PERSON;
The idea is: take the Person record with the issue and check who his/her Supervisor is. Then check who the Supervisor of that Supervisor is. Keep doing this until to reach the top. Ensure that a Supervisor doesn't loop back to a Person record.
If the problem still persists even after trying these suggestions, please contact IBM Maximo Support.
