  The SAP error message KW811, which states "The attribute to be changed is still required," typically occurs in the context of SAP's classification system, particularly when dealing with characteristics and classes in the classification of materials or other objects.
  Cause:
  This error usually arises when you attempt to change or delete a characteristic that is still marked as required for a class or object. In SAP, certain characteristics can be defined as mandatory, meaning that they must have a value assigned to them for the object to be valid.

  Solution:
  To resolve the KW811 error, you can follow these steps:

  Review Characteristic Settings:

  Assign Values:
  
  If the characteristic is required, ensure that all instances of the class have valid values assigned to this characteristic. You can do this through the material master or the object that is classified.
  
  
  
  Modify the Class or Characteristic:
  
  If you need to change the characteristic from required to optional, ensure that this change is acceptable within your business processes. After making the change, save your settings.
  
  
  
  Re-attempt the Operation:
