1. Navigate to the Job information of an employee > Change the Position > Save.
2. Workflow triggers
3. Proxy as the approver > approve the workflow > Application error occurs.

• Issue is caused due to the matrix relationships in the Position are swapped using the arrow marks which results in swapping of the external codes of one matrix relationship to another.
• This is not a supported use case as the external code is a key field and must not be swapped.

1. Withdraw the current workflow.
2. Go to the relevant Position and modify the external codes of the matrix relationships by either deleting or changing it, instead of swapping it.
3. Save
