• What is the cause and solution for SAP error message E2404 - Secondary key was copied ?

  The SAP error message E2404, which states "Secondary key was copied," typically occurs in the context of data entry or data processing within SAP systems, particularly when dealing with master data or transactional data that involves secondary keys.
  Cause:
  The error usually arises when:
  
  Data Duplication: There is an attempt to create or modify a record that already exists with the same secondary key. This can happen if the system is trying to copy data from one record to another, but the secondary key (which is often used for indexing or categorization) already exists in the target record.
  Configuration Issues: The configuration of the secondary key in the relevant data structure may not allow for duplicates, leading to this error when an attempt is made to copy or create a record with an existing secondary key.
  Data Integrity Constraints: The system enforces data integrity rules that prevent the duplication of secondary keys to maintain consistency and accuracy in the database.
  
  Solution:
  To resolve the E2404 error, you can take the following steps:
  
  
  Check Existing Records: Verify if the secondary key you are trying to use already exists in the database. You can do this by searching for the record using the secondary key in the relevant transaction or report.
  
  
  Modify the Secondary Key: If the secondary key is indeed already in use, consider modifying the key you are trying to enter to ensure it is unique.
  
  
  Review Configuration: If you have access to configuration settings, review the settings for the secondary key in the relevant module (e.g., Material Management, Customer Master, etc.) to ensure that it is set up correctly and allows for the intended use.
  
  
  Consult Documentation: Check SAP documentation or help resources for specific guidance related to the module you are working with, as the handling of secondary keys can vary between different SAP applications.
  
  
  Contact Support: If you are unable to resolve the issue, consider reaching out to your SAP support team or consulting with an SAP expert who can provide more tailored assistance based on your specific system configuration and business processes.
  
  
  Related Information:
  
  Transaction Codes: Depending on the context, you may be using specific transaction codes (e.g., MM01 for material creation, XD01 for customer creation) when encountering this error.
  SAP Notes: Look for relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
  User Authorization: Ensure that you have the necessary authorizations to create or modify records in the system, as lack of permissions can sometimes lead to unexpected errors.
