Create CN Configuration Assumptions
To create CNs in your SAP distribution targets, the following are assumed:
• The only fields that are configured as required are those that are consistently passed fromWindchill PDMLink to the SAP distribution targets.
• Company codes and plants are configured.
• The login used by the TIBCO connection has the appropriate roles assigned to it such as create material, change material, and create BOM.
• Required change master fields are maintained and those fields populated fromWindchill PDMLink data are not configured as locked.
• The material, BOM, and document object types are not configured as required.
• Change management is enabled for materials, BOMs, and documents.
• External assignment for change numbers is enabled.
• TheWindchill PDMLink attribute values are cross-referenced with the SAP distribution target values.
