True or False: An NDT can have undefined sources if parameters are not set correctly.

True or False: An NDT can have undefined sources if parameters are not set correctly.

• A. True
• B. False
• C. Only for custom views
• D. It depends on model configurations

Answer: (A)

An NDT, or Non-Display Table, can indeed have undefined sources if the parameters are not configured correctly. In Looker, when developing LookML models, sources must be defined for an NDT to successfully pull the required data. If parameters such as joins, views, or dimensions are missing or misconfigured, the NDT will not be able to reference the necessary data fields, resulting in undefined sources. This scenario highlights the importance of ensuring that all components and parameters relevant to an NDT are appropriately set to ensure it functions correctly. If there are errors or omissions in the configuration, the NDT will not have a valid source, leading to issues in data retrieval and analysis.
