LG overall

why not a kw arg instead? It would be more explicit.

@simahawk could you confirm that you want this kind of update :

`
def get_pos_ui_partner_pricelist_background(
self, pricelist_id, product_ids, base_pricelist=False
):
pricelists = super().get_pos_ui_partner_pricelist_background(
pricelist_id, product_ids
)

    # By design we do not calculate alternative prices on base pricelist
    if base_pricelist:
        return pricelists

    pricelist_rec = self.env["product.pricelist"].browse(pricelist_id)
    alternative_pricelists = []

    for alt_pricelist_rec in pricelist_rec.alternative_pricelist_ids:
        alternative_pricelists += self.get_pos_ui_partner_pricelist_background(
            alt_pricelist_rec.id,
            product_ids,
            base_pricelist=True,
        )

    if alternative_pricelists:
        return pricelists + alternative_pricelists

    return pricelists

`
