• What is the cause and solution for SAP error message CACSELT028 - Only customer fields may be changed in method &1 of BAdI &2 ?

  The SAP error message CACSELT028 indicates that you are trying to change fields in a BAdI (Business Add-In) method that are not allowed to be modified. Specifically, this message states that only customer fields can be changed in the specified method of the BAdI.
  Cause:
  This error typically occurs when:
  
  You are attempting to modify standard fields or system fields in a BAdI implementation where only customer-specific fields are permitted to be changed.
  The BAdI method you are working with is designed to allow modifications only to fields that are defined as customer fields (i.e., fields that are intended for customer-specific enhancements).
  
  Solution:
  To resolve this error, you should:
  
  
  Review the BAdI Documentation: Check the documentation for the specific BAdI and its methods to understand which fields are allowed to be modified. This information can usually be found in the SAP Help Portal or within the BAdI definition in the SAP system.
  
  
  Modify Only Customer Fields: Ensure that your implementation only modifies fields that are explicitly marked as customer fields. Avoid attempting to change any standard fields or system fields.
  
  
  Check Your Implementation Logic: If you are unsure which fields are customer fields, you can check the data dictionary (SE11) for the relevant structure or table to identify which fields are designated for customer use.
  
  
  Debugging: If you are still facing issues, you can debug the BAdI implementation to see which fields are being accessed and modified. This can help you pinpoint the exact line of code that is causing the error.
  
  
  Consult with SAP Support: If you believe that your implementation is correct and you are still encountering this error, consider reaching out to SAP support for further assistance.
  
  
  Related Information:
  
  BAdI (Business Add-In): A BAdI is a type of enhancement option in SAP that allows developers to add custom functionality to standard SAP applications without modifying the original code.
  Customer Fields: These are fields that are specifically designed for customer enhancements and are typically marked with a specific naming convention (e.g., Z or Y).
  Transaction Codes: You can use transaction codes like SE18 (to view BAdI definitions) and SE19 (to implement BAdIs) to work with BAdIs in SAP.
  
  By following these steps, you should be able to resolve the error and successfully implement your desired functionality within the constraints of the BAdI.
