The Constraint will be triggered on duplicating the invoice, if the pricelist is not the partner_id -> pricelist_id.

When we assign a custom pricelist, with a diffrent currency, the invoice cannot be duplicated.

"Pricelist and Invoice need to use the same currency."

account-invoicing/account_invoice_pricelist/models/account_move.py

Line 35 in 4be442b

raise UserError(_("Pricelist and Invoice need to use the same currency."))

I think the pricelist_id should be copy=True, but the pricelist is computed..
