• What is the cause and solution for SAP error message WA603 - Object type & not allowed for automatic type linkage ?

  The SAP error message:
  WA603 Object type & not allowed for automatic type linkage
  
  Meaning / Cause:
  This error occurs when you try to perform an automatic type linkage (automatic assignment or linking of object types) in SAP, but the object type you are attempting to link is not permitted for this automatic process. In other words, the system does not allow the specified object type to be automatically linked to another object type because it is either restricted or not configured for such linkage.
  Automatic type linkage is often used in scenarios like document management, classification, or object linking where certain object types can be automatically connected based on predefined rules or customizing.
  
  Common Scenarios:
  
  When linking equipment, functional locations, or other technical objects automatically in Plant Maintenance (PM).
  During automatic assignment of document types or classification objects.
  When using automatic object linking in Engineering Change Management (ECM) or Document Management System (DMS).
  
  
  Possible Causes:
  
  The object type you are trying to link is not included in the customizing settings for automatic type linkage.
  The object type is restricted by SAP standard and cannot be linked automatically.
  Missing or incorrect configuration in transaction codes related to object linking or classification.
  Custom object types that have not been properly set up for automatic linkage.
  
  
  Solution / How to Fix:
  
  
  Check Customizing Settings:
  
  Use transaction SPRO to navigate to the relevant customizing path for object linking or classification.
  For example, in Plant Maintenance:
  
  SPRO -> Plant Maintenance and Customer Service -> Maintenance and Service Processing -> Maintenance and Service Orders -> Functions and Settings for Object Linkage -> Define Object Types Allowed for Automatic Linkage
  Ensure that the object type you want to link is allowed for automatic linkage.
  
  
  
  Verify Object Type Configuration:
  
  Check if the object type is correctly defined and maintained in the system.
  For equipment and functional locations, check their configuration in the respective customizing areas.
  
  
  
  Adjust or Extend Object Types:
  
  If you are using custom object types, you may need to extend the customizing to include these types for automatic linkage.
  This might involve adding entries in tables or customizing nodes that control allowed object types.
  
  
  
  Check Authorization and User Exits:
  
  Sometimes, user exits or BAdIs might restrict automatic linkage for certain object types.
  Review any custom code or enhancements that might influence linkage behavior.
  
  
  
  Consult SAP Notes:
  
  Search for SAP Notes related to WA603 or automatic type linkage for your specific module.
  SAP Notes might provide patches or additional configuration instructions.

  Summary:
  The error WA603 indicates that the object type you are trying to link automatically is not permitted for such linkage. To resolve it, check and adjust the customizing settings to allow the object type for automatic linkage, verify object type configuration, and ensure no custom restrictions are in place.
