All actions: Do beneficiaries applying for MSCA have to provide Letters of Commitment with their applications?

Letters of Commitment are for entities not signing the Grant Agreement.

Beneficiaries submit the proposal and sign the Grant Agreement in case the proposal has been funded. Their commitment is already covered by the submitted application so they do not need to provide a Letter of Commitment. If a Letter of Commitment is not explicitly requested, it is not necessary to provide it.
