• What is the cause and solution for SAP error message PCA064 - External number assignment: only one planned order can be converted ?

  The SAP error message PCA064 ("External number assignment: only one planned order can be converted") typically occurs when you are trying to convert multiple planned orders into production orders, but the system is set up to allow only one planned order to be converted at a time. This is often related to the configuration of the number assignment for production orders.
  Cause:
  
  Number Assignment Configuration: The system is configured to use external number assignment for production orders, which means that each production order must have a unique number assigned to it. If the system detects that multiple planned orders are being processed simultaneously, it raises this error.
  Batch Processing: If you are trying to convert multiple planned orders in a batch process, the system may not allow this due to the external number assignment settings.
  User Authorization: Sometimes, user roles and authorizations can restrict the ability to convert multiple planned orders.
  
  Solution:
  
  Convert One Planned Order at a Time: The simplest solution is to convert each planned order individually rather than trying to convert them in bulk.
  Check Number Assignment Settings: Review the configuration settings for number assignment in the production order type. You can do this by navigating to:
  
  SPRO ? Production ? Shop Floor Control ? Master Data ? Order ? Define Order Types
  Check the settings for the order type you are using and ensure that it is set up correctly for your business needs.
  
  
  Change to Internal Number Assignment: If your business process allows, consider changing the number assignment from external to internal. This would allow the system to automatically generate order numbers, which may resolve the issue.
  User Authorization: Ensure that the user has the necessary authorizations to convert planned orders. Check with your SAP security team if needed.
  Consult SAP Notes: Check for any relevant SAP Notes that may address this issue or provide additional guidance.
