• What is the cause and solution for SAP error message /PLMI/GSS_B2B001 - Synchronization &1 is not in the external number range ?

  The SAP error message /PLMI/GSS_B2B001 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 SAP's Logistics and Supply Chain Management modules, particularly when dealing with external systems or interfaces.
  Cause:
  
  Number Range Configuration: The error suggests that the synchronization ID (represented by &1) is not found in the defined external number range. This could mean that the number range has not been properly defined or that the ID being used is outside the allowed range.
  Missing or Incorrect External Number Range: The external number range may not be set up correctly in the system, or the synchronization process is trying to use a number that has not been assigned.
  Data Consistency Issues: There may be inconsistencies in the data being synchronized, leading to attempts to use an invalid or non-existent number.
  
  Solution:
  
  
  Check Number Range Configuration:
  
  Go to the transaction code SNRO (Number Range Objects) in SAP.
  Look for the relevant number range object associated with the synchronization process.
  Ensure that the external number range is defined correctly and that it includes the range of numbers you are trying to use.
  
  
  
  Adjust Number Range:
  
  If the number range is not defined or is insufficient, you may need to create or extend the number range.
  Make sure that the number range is set to allow external numbers if that is required for your synchronization process.
  
  
  
  Review Synchronization Process:
  
  Check the configuration of the synchronization process to ensure that it is correctly set up to use the defined number range.
  Validate the data being sent or received during synchronization to ensure it adheres to the expected formats and values.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or notes related to the specific synchronization process you are working with. There may be specific guidelines or prerequisites that need to be followed.
  
  
  
  Testing:
  
  After making changes, perform a test to ensure that the synchronization process works as expected without generating the error.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as SNRO for number range management, SE11 for data dictionary, and SE37 for function modules that may be involved in the synchronization process.
  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.
  Community Forums: Consider visiting SAP community forums or discussion boards where similar issues may have been discussed, and solutions shared by other users.
  
  If the issue persists after following these steps, it may be beneficial to consult with your SAP Basis or technical team for further investigation.
