Hi Experts,

I have an item named "ITM001" in the organizations ORG1, ORG2, and ORG3. I need to switch off the item in the ORG1. That means preventing the item from selling in the ORG1. The following changes were made to item attributes.

Customer Ordered (MSTR Attribute) - Y

Customer Orders Enabled - MSTR : Y and ORG1 : N

With the above attribute changes, I can still add the item to a sales order.

What item's settings are required to stop selling that item in ORG1?
