Issue/Introduction

I am trying to import Contracts into CA Software Asset Manager. I am getting errors:
Invalid reference in field "import_contract_type_id" 
Invalid reference in field "import_contract_status_id" 
Invalid reference in field "import_customer_contact_con_id" 
Invalid reference in field "import_manufacturer_id" 

Environment

Release:
Component: CASAM

Resolution

The import ID field is required to import contracts. Verify that the Import ID's exist in the data file and are valid in the SAM application.
