while trying to update supervisor of a personnel number, following error has been fetched. I am unable to understand the root cause for this.
This error is coming only for this specific personnel number. We have no issue in updating supervisor of any other personnel number.
Please help me in finding the solution if you know the reason for this.
(Even updating supervisor manually is also giving runtime exception error. Ideally that should not be done. Am just mentioning it, so that the problem would be understood for the reader).
