I have a Reporting Services Project on SQL Server 2008 R2. The point is to provide users with a data model they can use as a data source for Report Builder 3. So I have created my data source views as usual and then the Report model with no problems.
For example in my model I have a table Student
which has a relationship with table Course
using a CourseSK
key (one to one). So I am using student.CourseSK = course.CourseSK
to return to the query designer only the course.Coursename
field under the Student
entity (I have hidden everything else from the course
table.)
The problem is that when I test it in ReportBuilder, using the query designer when I add field CourseName
from entity student
in the dataset, it returns two fields instead of one: CourseName
and Course
where course returns some values like AAAAAEAA =
. I guess is some object reference but can be very confusing to the end user. How can I make this disappear?
Indeed it turns out to be a unique entity identifier used for aggregating fields with non unique values. It cannot be removed from the data set. More information here Answer
