CacheLookup Table Property.

CacheLookup property value	Result
None	No data is cached or retrieved from the cache for this table. This property value should be used for tables that are heavily updated or where it's unacceptable to read outdated data.
NotInTTS	All successful caching key selects are cached. When in a transaction (after ttsBegin), no caches made outside the transaction are used. When inside a transaction, the record is read once from database and subsequently from the cache. The record is select-locked when read in a transaction, which ensures that the record cached is not updated while the transaction is active. A typical example of the NotInTTS property is on the CustTable in the Microsoft Dynamics AX application. It is acceptable to read outdated data from the cache outside a transaction, but when data is used for validation or creating references, it is ensured that the data is real-time.
Found	All successful caching key selects are cached. All caching key selects are returned from the cache if the record exists there. A select forUpdate in a transaction forces reading from the database and replaces the record in the cache. This is typically used for static (lookup) tables, such as Unit, where the record usually exists.
FoundAndEmpty	All selects on caching keys are cached, including selects that are not returning data. All caching key selects are returned from caching if the record exists there, or the record is marked as nonexistent in the cache. A select forUpdate in a transaction forces reading from the database and replaces the record in the cache. An example of FoundAndEmpty record caching is in the Discount table in the Microsoft Dynamics AX standard application. By default, the Discount table has no records. By using a FoundAndEmpty cache on this table, the keys that are queried for but not found are stored in the cache. Subsequent queries for these same non-existent records can be answered from the cache without a round trip to the database.
EntireTable	Creates a set-based cache on the server. The entire table is cached as soon as at least one record is selected from the table. For more information, see Set-based Caching.
