Specifically, the error states that the FORM routine for the specified formula or requirement does not exist.
  Cause:
  
  Missing FORM Routine: The most common cause of this error is that the FORM routine that is supposed to be executed for the characteristic is not defined in the system. This could happen if the routine was deleted or never created.
  Incorrect Configuration: There may be a misconfiguration in the settings related to the characteristic or the formula/requirement.
  Transport Issues: If the system has recently undergone a transport of changes, the FORM routine may not have been included in the transport request.
  Development Environment: If you are working in a development environment, the routine may exist in the production environment but not in the development environment.
  
  Solution:
  
  
  Check for the FORM Routine: 
  
  Go to transaction SE38 or SE80 and check if the FORM routine exists. You can search for the routine by its name.

  Create or Modify the FORM Routine:
  
  If the FORM routine is missing, you can create a new one using ABAP programming. Ensure that it meets the requirements of the characteristic and is correctly coded.
  If the routine exists but is not functioning correctly, review the code for errors or missing logic.
  
  
  
  Check Configuration:
  
  Review the configuration settings for the characteristic and ensure that it is correctly linked to the formula or requirement.
  Ensure that the characteristic is properly assigned to the relevant material or planning object.
  
  
  
  Transport Check:
