What is the one critical difference between normal calculated fields, and the calculated fields created after Data blending?

1. A. No difference, calculated fields cannot be created in Blends
2. B. Fields used in Blends must first be aggregated
3. C. The calculated fields created in Blends cannot be edited once created
4. D. The calculated fields created in Blends cannot use more than 2 fields

Correct Answer: B
Yes, due to the nature of blends, there are some conditions as follows from the official documentation that must be kept in mind while working with blends:


In addition to handling calculations slightly differently, there are some limitations on secondary data sources. You may not be able to sort by a field from a secondary data source, and action filters may not work as expected with blended data. For more information, see Other data blending issues.

True or False: When relating tables, the fields that define the relationships must have the same data type.

1. A. True
2. B. False

Correct Answer: A
According to the official documentation, the following are the requirements for using relationships:
1) When relating tables, the fields that define the relationships must have the same data type. Changing the data type in the Data Source page does not change this requirement. Tableau will still use the data type in the underlying database for queries.
2) You can't define relationships based on geographic fields.
3) Circular relationships aren't supported in the data model.
4) You can't edit relationships in a published data source.
5) You can't define relationships between published data sources.
6) Your workbook must use an embedded data source for you to be able to edit relationships and performance options in the Data Source page in Tableau Online or Tableau Server.
