Round Invoice Header.Invoice Amount to nearest 5000 dollars

Content

Our FinApInvoiceApproval rules are currently based on the Invoice Header.Invoice Amount but we have a requirement to round Invoice Header.Invoice Amount to nearest 5000.

In SQL it would be say select round(Invoice Header.Invoice Amount/5000,0)*5000 from dual but when we use round(Invoice Header.Invoice Amount/5000,0)*5000 in FinApInvoiceApproval the error "RUL-05716: The function "round" is not valid here." appears.

Any ideas how we can route the approval based on Invoice Header.Invoice Amount rounded to the nearest 5000?

Many thanks
