• What is the cause and solution for SAP error message C1051 - Allowed values overwritten for this object ?

  The SAP error message C1051, "Allowed values overwritten for this object," typically occurs in the context of SAP's configuration or data entry processes, particularly when dealing with characteristics and their allowed values in the context of variant configuration or classification.
  Cause:
  This error usually arises when:
  
  Inconsistent Data: The allowed values for a characteristic have been modified or overwritten in a way that conflicts with existing settings or data.
  Configuration Changes: Changes made to the configuration of characteristics or classes that lead to inconsistencies in the allowed values.
  Master Data Issues: Issues with the master data where the allowed values for a characteristic are not properly defined or are conflicting with other settings.

  To resolve the C1051 error, you can take the following steps:
  
  
  Check Characteristic Settings:
  
  Go to the transaction code CT04 (Change Characteristic) and verify the allowed values for the characteristic in question.
