Microsoft distributes Microsoft SQL 2008 R2 fixes as one downloadable file. Because the fixes are cumulative, each new release contains all the hotfixes and all the security updates that were included with the previous SQL Server 2008 R2 update release.
Consider the following scenario:
You create a Master Data Services (MDS) website on computer that has Microsoft SQL Server 2008 R2 MDS installed and configured.
You create a domain-based attribute for a leaf member and a domain-based attribute for a consolidated member. The attributes have the same domain entity for the MDS website.
Note The security permissions for the current user are applied at the entity or member level.
You open the entity in the Explorer area in Master Data Manager.
In this scenario, you might receive an error message that resembles the following:
A column named 'AttributeName' already belongs to this DataTable.
This issue occurs because of errors in the following functions that are used in the Explorer area in Master Data Manager:
