• What is the cause and solution for SAP error message WS405 - An internal error occurred during number assingment ?

  SAP Error Message:
  
  WS405 - An internal error occurred during number assignment
  
  Cause:
  The error WS405 typically occurs during the number assignment process in SAP, which is often related to document or object number ranges. The system tries to assign a number from a number range interval, but an internal inconsistency or error happens. Common causes include:
  
  Number range intervals are exhausted or incorrectly maintained: The number range interval for the object (e.g., documents, material numbers, etc.) might be fully used or not properly defined.
  Number range object inconsistencies: The number range object might be corrupted or inconsistent in the database.
  Locking issues: The number range object might be locked by another process, causing the assignment to fail.
  Authorization issues: The user or process might lack the necessary authorization to assign numbers.
  Custom code or user-exits: Custom enhancements or user-exits might interfere with the standard number assignment logic.
  Database inconsistencies: Underlying database problems or inconsistencies in number range tables (e.g., NRIV, NRIV2) can cause this error.
  
  
  Solution:
  
  
  Check Number Range Intervals:
  
  Use transaction SNRO or SNUM to check the number range object related to the error.
  Verify that the number range intervals are correctly defined and not exhausted.
  If intervals are exhausted, create new intervals or extend existing ones.
  
  
  
  Reset or Reinitialize Number Ranges:
  
  Sometimes resetting the number range buffers helps.
  Use transaction SNRO, select the object, and use the "Number Range Buffer" function to refresh.
  
  
  
  Check for Locks:
  
  Use transaction SM12 to check for locks on number range objects.
  If locks exist and are stale, consider deleting them carefully.
  
  
  
  Check Authorizations:
  
  Ensure the user/process has the required authorizations for number assignment.
  
  
  
  Review Custom Code:
  
  If custom enhancements or user-exits are involved in number assignment, debug or review them for errors.
  
  
  
  Database Consistency Checks:
  
  Run consistency checks on number range tables (e.g., NRIV, NRIV2).
  If inconsistencies are found, consult SAP Notes or Basis team for database repair.
  
  
  
  SAP Notes and Support:
  
  Search SAP Support Portal for notes related to WS405.
  Apply relevant SAP Notes or patches if available.
