The access_filter parameter requires which type of field names?

• A. partially scoped
• B. fully scoped
• C. globally scoped
• D. relatively scoped

Answer: (B)

The access_filter parameter requires fully scoped field names because it needs to explicitly identify the specific fields in the data model that are being referenced. Fully scoped field names include the view name and the field name, ensuring there is no ambiguity about which field is being used, especially in complex LookML models with multiple views that may have fields with the same name. Using fully scoped names provides clarity and maintains the integrity of the data access rules being applied. This is particularly important for security and data governance, where access can vary depending on the dimensions of the data being queried. This requirement helps ensure that filters are applied correctly across the relevant contexts in the LookML project. Other types of scoping, such as partially scoped or globally scoped, do not provide the same level of specificity and therefore are not suitable for defining access filters in LookML.
