This field indicates whether the attribute is linked automatically or manually to a record.
When the Attribute Value page is opened up for a record (an item, a store and so on), you can click Refresh Autom. Linked Attributes to link to the record attributes with Automatic Linking. For a manually linked attribute, you need to press Link Attribute in the page, select the attribute from the list of possible attributes and click OK.
In the Attribute Card page, the Link/Assign Default Values function can be used if Linking of the attribute is Automatic.
