By default, Magento will choose the price assigned to "ALL GROUPS" over the price assigned to a customer group if customer group's price is higher than ALL GROUPS price.
I want to override this logic and show the customer group's price even ALL GROUPS price is lower.
I just want to determine which class and method should I override for me to implement this. Any idea?
Did you checked vendor/magento/module-catalog/Pricing/Price/TierPrice.php class?
/**
* @param array $priceList
* @return array
*/
protected function filterTierPrices(array $priceList)
{
$qtyCache = [];
$allCustomersGroupId = $this->groupManagement->getAllCustomersGroup()->getId();
foreach ($priceList as $priceKey => &$price) {
if ($price['price'] >= $this->priceInfo->getPrice(FinalPrice::PRICE_CODE)->getValue()) {
unset($priceList[$priceKey]);
continue;
}
if (isset($price['price_qty']) && $price['price_qty'] == 1) {
unset($priceList[$priceKey]);
continue;
}
/* filter price by customer group */
if ($price['cust_group'] != $this->customerGroup &&
$price['cust_group'] != $allCustomersGroupId) {
unset($priceList[$priceKey]);
continue;
}
/* select a lower price for each quantity */
if (isset($qtyCache[$price['price_qty']])) {
$priceQty = $qtyCache[$price['price_qty']];
if ($this->isFirstPriceBetter($price['website_price'], $priceList[$priceQty]['website_price'])) {
unset($priceList[$priceQty]);
$qtyCache[$price['price_qty']] = $priceKey;
} else {
unset($priceList[$priceKey]);
}
} else {
$qtyCache[$price['price_qty']] = $priceKey;
}
}
return array_values($priceList);
}
