This error indicates that the system cannot find a valid number range for the specified logical system, which is necessary for generating or processing layouts.
  Cause:
  
  Missing Number Range Assignment: The logical system does not have a number range assigned for the layout.
  Configuration Issues: There may be a misconfiguration in the settings related to layout management or number ranges.

  To resolve the W+420 error, follow these steps:
  
  
  Check Number Range Assignment:
  
  Go to the transaction code SNRO (Number Range Objects).

  Ensure that a number range is defined and assigned to the logical system in question.
  
  
  
  Assign Number Range:
  
  If no number range is assigned, you will need to create a new number range or assign an existing one to the logical system.

  Cross-Application Components > Forms > Form Layout Management > Define Number Ranges.
  
  
  Here, you can create or modify the number range assignments.
  
  
  
  Check Logical System Configuration:
  
  Ensure that the logical system is correctly defined in the system.

  You may need to re-transport or manually configure the settings in the target system.
