• What is the cause and solution for SAP error message NGC_API_BASE018 - &:More than one object already classified with same characteristic values ?

  The SAP error message NGC_API_BASE018 indicates that there is an issue with the classification of objects in the SAP system. Specifically, it means that more than one object has already been classified with the same characteristic values, which violates the uniqueness constraint for the classification of objects.
  Cause:
  This error typically occurs in the context of SAP's classification system, where each object (such as a material, equipment, or document) is assigned specific characteristics and values. The system expects that each combination of characteristic values is unique for each object. If you attempt to classify a new object with characteristic values that are already assigned to another object, the system will throw this error.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Existing Classifications:
  
  Review the existing classifications in the system to identify which objects are already classified with the same characteristic values. You can do this by using transaction codes like CL02 (Change Class) or CL03 (Display Class) to view the class and its assigned objects.
  
  
  
  Modify Characteristic Values:
  
  If you find that the characteristic values you are trying to assign are already in use, consider modifying the values for the new object to ensure they are unique.
  
  
  
  Reclassify Existing Objects:
  
  If appropriate, you may choose to reclassify the existing objects that are causing the conflict. This could involve changing their characteristic values or moving them to a different class.
  
  
  
  Consult Documentation:
  
  Review the SAP documentation or help resources related to classification to ensure you understand the rules and constraints regarding object classification.
  
  
  
  Check Customizations:
  
  If your organization has custom classifications or enhancements, check if there are any specific rules or logic that might be causing this issue.
  
  
  
  Contact SAP Support:
  
  If you are unable to resolve the issue, consider reaching out to SAP support for further assistance. They may provide insights specific to your system configuration.
  
  
  
  Related Information:
  
  Classification in SAP: The classification system in SAP allows for the categorization of objects based on shared characteristics. Each class can have multiple characteristics, and each characteristic can have multiple values.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CL01 (Create Class), CL02 (Change Class), CL03 (Display Class), and CL24 (Display Characteristics) for managing classifications.
  Data Integrity: Maintaining data integrity is crucial in SAP systems, and understanding the classification rules helps prevent errors like NGC_API_BASE018.
  
  By following these steps, you should be able to identify the cause of the error and implement a solution to resolve it.
