Description
This property allows the more advanced linking between keys of two different dimensions.
The "Type" property of an Attribute-Loader allows the simple linking between two keys by searching the target-key with its id. But sometimes the source-Keyloader can't link to the target-keys with the id, because it is not possibility to load the target-id from its database or tables (or it might be too time-consuming because a couple of database-join would become necessary then).
In this case you might try to connect two keys by searching the target-key with one of its attributes which is known by the source-key. E.g. if the table you load the source-keys "Product" from has a column "MANUFACTURER_ID", you can link the products to their manufacturers by searching them with their ManufacturerID. Of course, the manufacturers must have a so called attribute, otherwise the system would raise an error.
Examples
Target-Attribute = "CustomerID"
Search the target-keys by its Customer-ID
