Configurable products not deducting stock properly

[BrentRobert]

The change underneath resulted in the creation of multiple itemRequests for configurableProducts.

When ordering a configurable product, a row is created for the simple and the configurable. However Magento uses the SKU of the simple for both on the order item. The mapping that was created above results in allowing configurable order items to be deducted on the SKU of the simple.

The reason this has been unnoticed is because the itemRequests are not grouped as in 'GetItemsToDeductFromOrder'. Magento loops over these requests and overwrites SKU based in the array. Always using the latest value. In this case the simple.

foreach ($inventoryRequest->getItems() as $item) {
    $normalizedSku = $this->normalizeSku($item->getSku());
    $itemsTdDeliver[$normalizedSku] = $item->getQty();
}

TLDR;

• The fix for grouped products actually broke the configurable ones.
• The itemRequests should be grouped by SKU

Thanks for your issue @BrentRobert If you have a PR to go with it that would be very much appreciated 👍

@convenient might you be able to add a test for grouped & configurable products?

Hi @BrentRobert, is this issue now resolved? You had a PR into the module but it's since been closed. Thanks

@tr33m4n I honestly have no idea. I closed the PR as it had been open for 2 years.
