This typically occurs in the context of Advanced Planning and Optimization (APO) in SAP, where characteristics are used to define the attributes of products or planning objects.
  Cause:
  
  Incorrect Configuration: The characteristic that is marked as required is not being populated correctly, and instead, an optional characteristic is being used.

  Solution:
  
  Check Master Data: Verify that the master data for the product or planning object includes the required characteristic and that it is populated correctly.
  Review Configuration: Ensure that the configuration settings in the APO system are correct. Check the settings for characteristics and ensure that the required characteristic is not mistakenly set as optional.
