A partial updates deployment must have the RECORD_SPEC attribute of one property set to TRUE. If no property is marked as the RECORD_SPEC property, the MDEX Engine will not process partial updates.

The RECORD_SPEC attribute specifies the property that is used to identify specific records in partial updates. For example, you may wish to use a field such as UPC, SKU, or part number to identify a record. You may set the RECORD_SPEC attribute’s value to TRUE in any property where the values for the property meet the following requirements:

Only one property in the project may have the RECORD_SPEC attribute set to TRUE. All updates that add new records must include a valid value (that is, a value that fulfills the above criteria) for the RECORD_SPEC property.
