Hi Sebastian,You can use the following side effect to refresh only a specific column for all items: side effects { field Quantity affects field _Header._Item.Price; } Best Regards,Maryia

 Hi Sebastian,You can try to change your side effect for the Item entity to the following: side effects { field Quantity affects entity _Header._Item; } All items will be refreshed after changing the Quantity for Item. Best Regards,Maryia
