Sending project on Invoice line on a pre-booked invoice results in error but works in GUI

[Gabriel Acosta]

We get an error when using supplierInvoice PUT endpoint on a pre-booked invoice where we try to set projectId on a line.

Error: {"message":"Error updating supplier invoice. ProjectId field on invoice 200078 cannot be updated because it is Pre-booked."}

In GUI you can change project and project task on the invoice without an issue. Is this a bug?

Awesome! thanks for the fast response!

Hello, 

we confirm that Project & Task in the Supplier Invoice line is editable when the invoice is pre-booked, so that API should follow the same flow. This has been reported to our development team.
