Questions

Overriding the default context can be essential for various reasons, depending on the goals you want to achieve with your data analysis. Here are the specific reasons with explanations:

1. To create measures that behave according to your intentions, regardless of what the user selects:

   • This is vital when you want to ensure specific calculations or business rules are applied consistently. For example, if you want a particular measure to always consider a specific time frame or set of data, overriding the default context ensures that the measure behaves as intended no matter what filters or selections the users choose.

2. To create measures that do not summarize or average:

   • At times, you might need measures that reflect a different type of calculation than the default summarization. By overriding the context, you can create measures that provide a distinct analytic outcome, such as displaying the maximum, minimum, or a custom-calculated value that doesn't fit into standard summarization functions like average or sum.

3. To create new relationships:

   • Overriding the default context allows you to define your relationships between data sets. This can be particularly useful when you need to perform complex joins or unions in data sets that aren't naturally related in the default context. It helps in creating more refined, accurate insights and analyses by establishing the necessary relationships that suit your analysis requirements.

In summary, overriding the default context provides flexibility and precision in how data is analyzed and presented, ensuring that the measures and relationships you create align closely with your specific analytical goals and requirements.
