Specifies whether an INSERT operation should perform an upsert by checking the ExternalId.

Data Type

bool

Default Value

false

Remarks

When this property is set to true, INSERT operations check for an existing record using the ExternalId field:

• If the specified ExternalId already exists in NetSuite, the existing record is updated.
• If the ExternalId does not exist, a new record is created.

When this property is set to false, INSERT operations always attempt to create a new record. If a record with the specified ExternalId already exists, the operation fails with a "This record already exists" error. The record is not updated, even if ExternalId matches an existing one.

This property applies only when Schema is set to SuiteTalk.
