Honda Civic Replacement Key – Model 2007-2010

In AX 2012, a surrogate key is the auto-generated primary key for a table in the database. The surrogate key is linked to the already existing RecId field within any table. This means that the surrogate key is a unique 64-bit integer value that is mandatory for the table and cannot be changed or have duplicates. The fact that it is a 64-bit integer (int64) value means table operations normally perform faster than other types of field such as string fields. This is the main strength of surrogate keys.

WHAT IS A REPLACEMENT KEY INDEX?

While a surrogate key is great for lookup and database performance, it is not useful for the end-user because it gives no indication of the table’s purpose, or what related tables it is linked to. For this reason, AX 2012 has added the ‘Replacement Key’ index property for tables. The replacement key index is a dropdown of alternate keys that have been specified for the table. There can be any number of alternate keys for a table but only a single replacement key. More than one field can be specified under a replacement key, and it is these fields that will be displayed to the end-user on a form instead of the surrogate key field.
