Notes
•The relationship can sort the related records so that the first related record (the record the lookup will copy) is a particular record. For example, to look up the most recent checkout date for a particular piece of equipment, sort records in descending order by checkout date.
•When data in the related table changes and you want the current table to contain the new values, you can look up the data again. See
Updating lookup values.
Important When a lookup is based on a multi-criteria relationship, a lookup will be triggered each time a value is entered into any of the fields that are involved in the multi-criteria relationship. The lookup is being performed each time a value is entered into one of the required fields. When all of the requisite fields have values, the final lookup value will be copied into the lookup target field.
