KB2975322 - FIX: Blank value is set to NULL value in a business rule in MDS of SQL Server 2012 or SQL Server 2014

Symptoms

Assume that you use business rules in Master Data Services (MDS) of Microsoft SQL Server 2012 or SQL Server 2014. When a business rule sets an attribute value to blank, it sets the blank value to a NULL value on the database side. In this situation, when another business rule evaluates whether the attribute is blank, it does not equate a NULL value with a blank value.

Each new cumulative update for SQL Server contains all the hotfixes and all the security fixes that were included with the previous cumulative update. Check out the latest cumulative updates for SQL Server:


Workaround

To work around this issue, append checking condition "OR Attribute is equal to ~NULL~" in the business rule when you evaluate whether an attribute is blank.

Status

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
