How to change an expenditure organisation on a purchase order?

Issue: We have a number of invoices that we are unable to pay via the system and record the transaction. The error message generated by the system is that “The expenditure organization doesn’t exist in the expenditure organization hierarchy of the expenditure business unit”.

Example of the error message below:

Upon reviewing the purchase orders/ Requisitions none of them have an expenditure organisation listed but they are all coded to projects. It appears that the requisitions have taken on the expenditure organisation linked to the department that the requisitioner worked for.

We had an organisational change in August which meant that some departments were closed, and this has now had an impact on being able to process payables transactions, even though the financial coding details exist such as cost centre and project exists are active.
