CMS Application - Modules - Module content overview - User Defined Modules - Fatal Error - Module content overview failed

Doing a Module content overview from CAST-MS, we might get the following error:

User Defined Module - Module content overview failed
User Defined Module - Module content overview failed
Source Server / XXXX-XXXX / XXXX-XXXX FullContent: 'XXXX-XXXX' needs to be analyzed before taking the snapshot.
Continue with the option 'Skip Analysis Job' may lead to incomplete results

This error can come up from two possible scenario if you are trying to view the module content and 

1. You are trying to execute the analysis by Analysis units one after other and there is at least one Analysis Unit which has not been executed.
   Solution: You should run the execution of all the analysis units and then try to overview the content of the module.
2. The analysis has not been run or has failed and you are still trying to view the content of the module.
   Solution: You should run the Analysis completely and then try to view the content of the module.
