Why does product definition table have multiple PPN with unique PPN numbers but all other attributes having same value.SummaryPPN/SKU is a combination of entitlement like Publisher+Product+Edition+Version+Langauge+Platform+Volume+Location+Prod/Non Prod+ could be many other thingsIn the current data model for part numbers, the system[Content Code] only captures Publisher+Product+Edition+Version and hence, these might look the same. All these PPNs are valid PPNs by Microsoft Corporations and none of the PPN is duplicate.Every end customer buys a particular PPN and that can be used for the requirement.if the PPN which you has is unavailable in Content Library, then kindly raise a case with Servicenow to add the same to Content Library.
