Question:  If I have more than one customer that uses the same MPN, how do I "Disallow Part from Purchasing/Kitting"  for only one of the customers?

Answer:  If the part is listed on the BOM as a customer/consigned item then it is controlled by the "Disallow Part from Purchase/Kitting" option within the Customer Level of Inventory Control Management.  If the part is a BUY part on BOM(s) for different customers the Kitting module is controlled by the "Disallow Part from Purchase/Kitting" option within the Inventory Control Management module   Since it is BUY on the BOM the system is looking at the BUY settings.  For further detail see Article #3211 .  For Buy parts that are used for multiple customers we recommend that you un-check that AVL so it is no longer approved at the BOM's level for that product.
