PF: Which unit contribution covers the secondments costs in a Postdoctoral Fellowship?

On p. 36 of the MSCA Financial guide, it is written that:

“The research, training and networking contribution covers costs related to the training and research expenses of researchers/staff members as well as costs related to the transfer of knowledge and networking activities (e.g. costs for participation in conferences, trips related to work on the action, training or language courses, seminars, lab material, books, library records, publication costs, visa-related fees, even if incurred before the recruitment date) as well as:

− MSCA-DN: additional costs arising from each secondment of six months or less, which requires mobility from the place of residence (e.g. travel and accommodation costs)

− MSCA-PF: additional costs arising from secondments, non-academic placements and outgoing phase in MSCA-PF GF.”
