Rejection Code F73: Invalid amount type/boundary code:budgeted by PA period

We recently tried transferring internal costs from one project to another and received an error. There were multiple tasks on the project and some of them transferred with no issues while two did not. This is something we do regularly with no issues.

The rejection code we got was F73 and the Rejection Reason was: Invalid amount type/boundary code:budgeted by PA periods. I have been trying to find more information on either the rejection code or reason to get a better understanding of what went wrong but I have not been successful.

Is anyone familiar with this Rejection Code and what a solution might look like to correct it? I apologize if I'm missing any key information in my question, but would be happy to provide it if needed.
