DN: A declared PIC was used by mistake for a beneficiary in a Doctoral Networks proposal instead of the validated one. Does the applicant need to notify anyone of this and could they be penalised?

The applicant should notify the European Commission through the IT Helpdesk and mention the proposal number. This inaccuracy does not affect the evaluation. As far as the host organisation is well identified, it should not be a problem to correct the PIC number later. Of course, this should be reported as soon as possible after the start of the grant preparation phase.
