Smart SAP Assistant

• What is the cause and solution for SAP error message NGC_API_BASE008 - Classification data of &1 (&2) can only be maintained using a change num. ?

  The SAP error message NGC_API_BASE008 indicates that you are trying to maintain classification data for a specific object (identified by &1 and &2) without using a change number. This is a common scenario in SAP when working with classification data, particularly in the context of materials or other objects that require version control.
  Cause:
  The error occurs because the system is configured to require a change number for maintaining classification data. Change numbers are used in SAP to track changes to objects over time, ensuring that modifications are documented and can be reverted if necessary. This is particularly important in environments where strict change management processes are in place.
  Solution:
  To resolve this error, you need to follow these steps:
  
  
  Use a Change Number: When you attempt to maintain the classification data, ensure that you are using a valid change number. You can create a change number if one does not already exist.
  
  
  Access the Change Number: 
  
  Go to the transaction code related to the object you are trying to change (e.g., MM02 for material master).
  Before making changes, enter the change number in the appropriate field.
  
  
  
  Check Configuration: If you believe that the change number should not be required, you may need to check the configuration settings in your SAP system. This can typically be done by:
  
  Navigating to the relevant customizing settings in SPRO.
  Checking the settings for classification and change management to see if the requirement for change numbers can be modified.
  
  
  
  Consult Documentation: If you are unsure about how to create or use change numbers, refer to the SAP documentation or help resources specific to your version of SAP.
  
  
  Contact Support: If the issue persists or if you are unsure about making changes to the configuration, consider reaching out to your SAP support team or a consultant who specializes in SAP classification and change management.
