To enable data caching on a worksheet, you should minimize the dynamic content that can cause the cache to become outdated quickly. Removing hierarchy columns can improve performance because hierarchies often involve complex joins and calculations that can slow down data retrieval. Disabling the "Use As Reference" checkbox on the Part column means that changes in the Part table will not cause the cache to be invalidated, which can be beneficial if the Part data does not change frequently.

If each order is associated with a single salesperson and the goal is to filter records by the salesperson's name, the most straightforward solution is to add a field directly to the DemandOrder table where orders are recorded. This avoids unnecessary joins to another table and simplifies the data model. According to database normalization principles, if the field is non-repetitive and directly related to the entity (in this case, the order), it should be placed on the same table.

ReferencesThe addition of a single attribute that is not multi-valued, non-repeating, and directly related to the primary key in the table aligns with the first normal form (1NF) in database normalization. This approach is also supported by Kinaxis best practices for efficient data retrieval.

To provide a worksheet based on the CRPOperation table that reports the destination location and to view all valid work centers that feed a given stock location:

• Statement B:Create a reference field on the CRPOperation table to the Location table. This approach establishes a direct relationship between operations and their respective locations, enabling efficient reporting and querying capabilities for the secondary requirement of viewing work centers related to a stock location.

Creating a reference field on the CRPOperation table to the Location table (B) is the most efficient way to report destination location while allowing visibility of all valid work centers that feed a given stock location.

• The Kinaxis RapidResponse documentation suggests that creating direct references between tables ensures better performance than creating additional lookup tables or worksheets23.

A. In the ItemDetail table, making Name plus Site a compound reference to the Item table aligns with relational database principles where a foreign key references a primary key in another table.

C. In the TransactionDetail table, making ID, Owner, and Type a reference to the TransactionHeader table follows the foreign key to primary key relationship as well, where TransactionDetail refers to its header record.

E. In the TransactionDetail table, making ItemName plus ItemSite a reference to the Item table ensures that each transaction detail record is linked to an existing item record, enforcing referential integrity.

B is incorrect because the TransactionHeader table should not reference the TransactionDetail table; it should be the other way around. D is incorrect because the Item table should not reference the ItemDetail table; this too should be the other way around.
