Record specifier attribute required for partial updates

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:

The value for this property on each record must be unique.
Each record should be assigned exactly one value for this property.

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.
