• What is the cause and solution for SAP error message WAB068 - External number assignment not implemented (number range &1 &2) ?

  The SAP error message WAB068 indicates that there is an issue with external number assignment for a specific number range. This typically occurs when the system is trying to assign a number from a number range that is configured for external number assignment, but the necessary implementation or configuration has not been completed.
  Cause:
  
  External Number Assignment Not Implemented: The number range you are trying to use is set up for external number assignment, but the system does not have the necessary logic or implementation to handle this assignment.
  Configuration Issues: The number range may not be properly configured in the system, or the relevant settings for external number assignment may be missing.
  Missing User Exits or BAdIs: If there are user exits or Business Add-Ins (BAdIs) that are supposed to handle the external number assignment, they may not be implemented or activated.
  
  Solution:
  
  
  Check Number Range Configuration:

  Implement External Number Assignment Logic:
  
  If the number range is intended for external assignment, you may need to implement the logic to handle this. This could involve creating a custom function module or using existing user exits/BAdIs.
  Check for any documentation or guidelines provided by SAP regarding the implementation of external number assignment for the specific number range.
  
  
  
  Review User Exits and BAdIs:
  
  Check if there are any user exits or BAdIs related to the number range that need to be implemented.
