We have two main subsidiaries for our customers using our SuiteCommerce site, X and Y. In my Sandbox environment, if I have an item's subsidiary set for Y only, then it only shows for Y customers and not for X customers. If I do the same action in my prod, the item is no longer available for any customer - the only way to have the item come back for either customer is to ensure X is selected as a subsidiary on the item.
Our sandbox has just been refreshed in the last month, so my test Y customer and test Y items are exact duplicates. I haven't been able to find anything for additional places to look for subsidiary based item showing. Any assistance is appreciated, if available!
