I am working on a Magento 2 site where we are using a Warehouse management system that manages stock. With it being an old system the only way to obtain latest stock is running a CSV from it at periods through the day. This export includes ALL stock, here lies the problem.
When using the Magento 2 import functionality and using add/update it is adding all the products on the original CSV into the database. Ideally all we want is an 'update' option, is this possible?
So ideally the csv could have a number of different SKU's that may or may not be on the site currently. If they are the Stock value gets updated, if not then it simply skips over it.
Any help would be greatly appreciated.
