Salesforce Loyalty Management: "INVALID_CROSS_REFERENCE_KEY: invalid cross reference id" when loading or querying Transaction Journal external IDs

Possible Cause 1: The referenced parent or lookup record is missing from the job.

• Identify the lookup/foreign-key field named in the error.
• Confirm the parent record exists in the target org by querying it.
• Add the parent object and the lookup relationship to the same data load or seeding job so the parent is created or resolved before the child record is inserted.
• Re-run the load with the parent included first.

Possible Cause 2: The running user lacks access to the referenced record or Record Type.

• Go to Setup > Users > Permission Sets for the API/integration user.
• Grant access to the referenced Record Type via Setup > Object Manager > <Object> > Record Types, then assign it to the user's profile or permission set.
• If the error reads "Record Type ID: This ID value is not valid for the user", assign that Record Type  to the user.
• As a workaround , Try assign "View All Data"/  "Modify All Data" permission to the user via the permission set, then re-test.
