A data architect adds a field to an existing data model that contains new values for the ProductGroup. The business analyst needs to efficiently update the app and meet these requirements:
✑ Use the existing charts, which are built using a master item dimension called ProductGroup
✑ Existing charts must use the new values for ProductGroup
✑ Business users must be able to compare the new and old values
How should the business analyst meet these requirements?
To meet the requirements, the best approach is to change the ProductGroup dimension to use the new field, and then create a new master dimension for the old field. This allows the existing charts to utilize the new values while keeping the old values accessible for comparison. This method ensures that all existing charts are updated to reflect the new ProductGroup values and also provides the ability to compare old and new values effectively.
From learning.qlik: Your answer is correct. The correct answer is: Change the ProductGroup dimension using the new field, and create a new dimension in the master items for the old field
By updating the old master dimension to reference the new field, and creating a new master dimension for the old field, you ensure that the existing charts use the new values, and that business users can easily distinguish between old and new values (by utilizing the different master dimensions)
