• What is the cause and solution for SAP error message /PLMI/GSS_I2B001 - Synchronization &1 is not in the external number range ?

  The SAP error message /PLMI/GSS_I2B001 Synchronization &1 is not in the external number range typically indicates that there is an issue with the external number range configuration for a specific synchronization process in the SAP system. This error often arises in the context of integration scenarios, such as those involving SAP Cloud Platform Integration (CPI) or other middleware solutions.
  Cause:
  
  
  Number Range Configuration: The error suggests that the synchronization process is trying to use a number that is not defined in the external number range. This could happen if:
  
  The number range for the specific object is not defined or is incorrectly configured.
  The number range has been exhausted, meaning all available numbers have been used up.
  The synchronization process is trying to access a number range that is not assigned to the relevant object.
  
  
  
  Data Consistency Issues: There may be inconsistencies in the data being synchronized, leading to attempts to use invalid or non-existent identifiers.
  
  
  Authorization Issues: Sometimes, the user or process attempting the synchronization may not have the necessary authorizations to access the number range.
  
  
  Solution:
  
  
  Check Number Range Configuration:
  
  Go to transaction code SNRO in SAP.
  Look for the relevant number range object associated with the synchronization process.
  Ensure that the number range is defined correctly and that there are available numbers in the range.
  
  
  
  Adjust Number Range:
  
  If the number range is exhausted, you may need to extend it by creating a new interval or increasing the existing range.
  Make sure that the number range is assigned to the correct object type.
  
  
  
  Review Synchronization Logic:
  
  Check the logic of the synchronization process to ensure that it is correctly referencing the number range.
  Validate the data being synchronized to ensure it adheres to the expected formats and values.
  
  
  
  Authorization Check:
  
  Ensure that the user or service account executing the synchronization has the necessary authorizations to access the number range.
  
  
  
  Consult Documentation:
  
  Review any relevant SAP documentation or notes related to the specific synchronization process you are working with, as there may be additional configuration steps or considerations.
  
  
  
  Related Information:

  SAP Notes: Check SAP Notes for any known issues or patches related to the error message. You can search for the error message or related keywords in the SAP Support Portal.
  
  
  Logs and Traces: Review application logs (transaction SLG1) and system logs for additional context around the error, which may provide more insights into the root cause.
  
  
  By following these steps, you should be able to identify and resolve the issue related to the error message /PLMI/GSS_I2B001 Synchronization &1 is not in the external number range.
