• What is the cause and solution for SAP error message W/138 - Internal number assignment. Planning number was deleted ?

  Certainly! Here's a detailed explanation regarding the SAP error message:
  
  SAP Error Message:
  W/138 Internal number assignment. Planning number was deleted
  
  Cause:
  This warning message typically occurs during the creation or processing of a production order, maintenance order, or similar document that involves internal number assignment for planning numbers (such as order numbers, reservation numbers, or other internal document numbers).
  
  The system tries to assign an internal planning number (e.g., order number) automatically.
  However, the planning number that was previously assigned or reserved has been deleted or is no longer valid.
  This can happen if the number range object associated with the planning number was changed, reset, or if the number was manually deleted or removed from the system.
  It may also occur if there is a mismatch or inconsistency in the number range intervals or if the number range object is not properly maintained.
  
  
  Solution:
  
  
  Check Number Range Intervals:
  
  Go to transaction SNRO or SNUM (depending on SAP version).
  Enter the relevant number range object (e.g., AUFNR for production orders).
  Verify that the number range intervals are correctly defined and active.
  Ensure that the current number is within the defined interval and has not been deleted or reset improperly.
  
  
  
  Check Number Assignment Settings:
  
  Verify the configuration for internal number assignment in the relevant customizing path.
  For production orders, check under:
  
  SPRO ? Production ? Shop Floor Control ? Master Data ? Order ? Number Ranges
  
  
  Ensure that the number assignment is set to internal and that the number range object is correctly assigned.
  
  
  
  Check for Manual Deletion or Inconsistencies:
  
  Investigate if the planning number was manually deleted or if there was a system cleanup that removed number assignments.
  If so, restore or reassign the number range intervals properly.
  
  
  
  Recreate or Reset Number Range:
  
  If the number range is corrupted or inconsistent, you may need to reset or recreate the number range interval.
  Be cautious with this step as it can affect document numbering integrity.
  
  
  
  Check for OSS Notes or SAP Support:
  
  Sometimes, this warning can be related to known SAP bugs or patches.
