  The SAP error message VCH_HL_CORE018 indicates that there is an issue with clearing a mandatory characteristic in a specific instance. This error typically arises in the context of handling data in SAP systems, particularly when working with characteristics in a data model or during data processing tasks.
  Cause:
  The error occurs when an attempt is made to clear a mandatory characteristic (denoted by &1) of a specific instance (denoted by &2) that cannot be cleared due to business rules or data integrity constraints. This could happen for several reasons, including:
  
  Mandatory Characteristics: The characteristic in question is defined as mandatory, meaning it must always have a value. Attempting to clear it violates this rule.

  Solution:
  To resolve this error, consider the following steps:
  
  
  Check Characteristic Definition: Review the definition of the characteristic in the data model to confirm that it is indeed marked as mandatory. If it should not be mandatory, consider changing its configuration.
  
  
  Review Dependencies: Investigate any dependencies or relationships that may be preventing the clearing of the characteristic. Ensure that all related data is in a valid state.
  
  
  Data Validation: Ensure that the data being processed adheres to the business rules defined in the system. If the characteristic must retain a value, ensure that a valid value is provided instead of attempting to clear it.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on handling mandatory characteristics and the implications of clearing them.
  
  
  Error Logs: Check system logs or error messages for additional context that may help identify the root cause of the issue.
