PIVOT Transformation Issue in SSIS

Today I’ve found a bug in SSIS Pivot Transform component reported as a question in TechNet forums here.

Reported issue was related to pivoting some records based, result of PIVOT transformation in SSIS was not as expected to be. read below for detailed explanation;

Scenario Explanation:

This is a sample of incoming data set:

The expected output after pivot with Month as Set Key, and Test as Pivot Key is :

But the problem is using PIVOT transformation generates the output below:


This issue occurred because SSIS Pivot Transformation consider the
ORDER or records base on the SET Key, in this example Set key is Month, and data rows are not sorted by month, so result of using Pivot transformation will be as below (which is wrong result set):

Resolution (Work around):

sorting incoming data set based on the Set key before the Pivot transformation is the work around for this issue. sorting can be done with Order by clause in the source query, when you are fetching data from databases. But in this example we fetch data from excel, so we use SORT Transformation. and sorting based on Set key in this example means sorting based on Month, after sorting we redirect result to Pivot transformation. here you can see result (as expected and correct):
