Which of the following methods can restrict data entry to users?

The method that effectively restricts data entry to users is identified as Valid Intersections. This approach establishes a framework that ensures users can only input data into designated cells that meet certain criteria based on the intersection of dimensions. By defining which combinations of dimension members are valid for data entry, organizations can streamline the data input process and enhance the accuracy of their data, as users will be guided to enter information only in the appropriate contexts.

Utilizing Valid Intersections is particularly beneficial in complex planning scenarios where there might be numerous combinations of dimensions, and not all of them should allow data entry. This control mechanism prevents erroneous data entry and maintains the integrity of the data model.

While other methods, like Read-only States and Dimension Restrictions, can influence user access in various ways, they do not specifically restrict data entry in the same direct manner as Valid Intersections, which are designed explicitly to define valid data entry options. Default Members establish default selections but do not inherently limit where data can be entered, and those aspects may not create restrictions in the same context as Valid Intersections do.
