Can the expenditure organisation of the employee be different from that of the project

We have a requirement where a supporting business unit has few employees which need to expense against a project defined in main business unit.

The employee has project team member role and a job and department which are setup as project expenditure organisations.

However, what we need is to expense against a project which has a different expenditure organisation and when we are trying to save the expense report, we get below errors

You must provide an expenditure organization for this transaction. (PJC-2220145)

Error

The human resource assignment for the transaction doesn't exist. (PJC-2220377)

Error

A job isn't defined for the person assignment in the human resources application. (PJC-2220499)
