The bug paradox: When fixing the bug leads to wrong reports

My workmate Christoph Gnodtke wrote an excellent blog about how to identify SAP BusinessObjects Web Intelligence reports which are impacted by various calculation changes in newer BO versions. What I would like to point out here is that not only BO 4.x migrations are concerend but also “simple” service / support package upgrades e.g. from XI 3.1 SP2 to SP6. In my current customer case we’ve found many many reports which obviously were created in a wrong way, namely that the table structure contains the merged dimension (e.g. [Merged Country]) where as the cells within the row use a variable containing e.g. a Where operator using the original dimension ([Query1].[Country]). In our case the business requirement would have been to use the merged dimension here as well. As outlined here, in former BO support package levels a bug resulted in the effect, that the just mentioned example still showed what the business expected. Now (e.g. in XI 3.1 SP6) that the bug is fixed, the reports start to show wrong values. Although the software 360Eyes doesn’t solve the problem, it at least helps to identify concerned reports. Unfortunately we still need to look into every single report and compare between the version running on the XI 3.1 SP2 environment and the SP6 environment. In order to speed up this process we use 360Cast. This software provides similar features like BO Publications e.g. for report scheduling and bursting. The main advantage namely in the case of report testing are two fold (compared to BO out of the box features):

  1. Report selection for a schedule job can be done using good old BO categories. That means you can assign e.g. a test category to all reports you want to test in one single run. In our customer case we use categories for each data mart. In 360Cast, instead of choosing every single report individually, we just choose to select all reports of this test category.
    In order to run all these reports with one single click there is just one thing missing: Providing all the necessary prompt values, often the same values for the same prompts (like Year) over many reports. This is where the second advantage comes into play:
  2. To provide prompt values 360Cast accepts both manual input values (where a value can be applied to a all prompts with the same name) but also values from an Excel sheet (or even from an SQL query). We usually use the Excel alternative. Based on this we can easily vary input parameters for different test purporses by simply using another Excel sheet. In addition we can specify the export format and the recipients, e.g. by providing an email address.
    (The values in the drop down menues correspond to the columns in the underlying Excel spreadsheet)

After all, also 360Cast doesn’t solve the initial problem. But at least we don’t need to run every report (identified by 360Eyes earlier) on its own but can automate the refresh process and we can easily rerun reports (e.g. with different prompts by simply modifying the values in the Excel list).
