Cognos Active Reports Tips

Version: Cognos 10.2.2

 Problem:
While running Active Report from Report Studio, sometime we get error in loading chart:
2204 An error occurred. " ActualWidth.
Cause:
Potential Browser issue in rendering while multiple mhtl files are already opened.
Solution:
  • Close Other mht files or,
  • Run in schedule mode and verify that there is no other issue with charts


Naming Conventions:

In Cognos Active Reports, we can follow below naming convention for easy maintenance


1. Name all Controls - DataItem__ControlName
2. Associated Queries - DataItem__ControlName_Query
3. Variable - starts with "v"
4. Parameters - starts with "p"

Share as Public variable so that CWA can use them.


Application Drill Through:

For passing parameters from summary Active Report to Detail Active Reports, we can use public variable, application drill through and Data deck in detailed report.

This design is useful when volume is high and we need to break reports and user needs offline consumption. Along with this, create a job to push to mobile device all reports together so that links are not broken.

Cognos: How to replace an existing report without breaking links?

Below IBM document explains behavior of copy/move or overwriting impact of objects:- https://www.ibm.com/support/knowledgecenter/en/SSEP7J_11.0.0/com.ibm.swg.ba.cognos.wig_cr.doc/c_gtstd_copy_move_items.html If you copy and overwrite an existing report, the copied report ID and links replace those of the existing report. In this case, you might need to update links, such as links to job schedules. If you move and overwrite an existing report, the existing report ID and links are maintained. In this case, references to the moved entry are broken. However, this doesn't work in all cases and we see drill through links broken in some cases. Best approach in such case is to use cognos deploy method where you update reports in separate folder in same environment and import it to destination location. You can create single export and import tasks to use for all such updates.
