Thank you @craigcarnell for reporting the issue

Some records from M1 > cataloginventory_stock_item table were not transferred to M2 > inventory_source_item. To find them you can look at the method \Migration\Step\Inventory\Model\SourceItem::prepareSelect() . So either there are some records in cataloginventory_stock_item with website_id != 0 or records catalog_product_entity.entity_id =! cataloginventory_stock_item.product_id

@craigcarnell was it a bug of the tool?

[csdougliss]

@victor-v-rad There was a few entries in M1 catalog_product_entity which had no sku which was the cause.
