• What is the cause and solution for SAP error message CZ090 - & & already exists ?

  The SAP error message "CZ090 & & already exists" typically indicates that there is an attempt to create or modify an entry in the system that already exists. This error can occur in various contexts, such as when dealing with master data, configuration settings, or transactional data.
  Cause:
  
  Duplicate Entry: The most common cause is that the system is trying to create a new entry (like a material, vendor, or customer) that has the same key or identifier as an existing entry.
  Data Migration Issues: If data is being migrated from another system or imported in bulk, duplicates may arise if the data is not properly cleansed.
  Configuration Errors: In some cases, configuration settings may allow for duplicate entries, leading to conflicts.
  
  Solution:
  
  Check Existing Entries: Before creating a new entry, check the existing records to ensure that the entry you are trying to create does not already exist. Use transaction codes relevant to the data type (e.g., MM01 for materials, XK01 for vendors).
  Modify Existing Entry: If the entry already exists and you need to make changes, consider modifying the existing record instead of creating a new one.
  Data Cleansing: If you are importing data, ensure that your data is cleansed and duplicates are removed before the import process.
  Error Handling in Custom Programs: If this error arises from a custom program or report, review the logic to ensure it properly checks for existing entries before attempting to create new ones.
  Consult Documentation: Refer to SAP documentation or help resources for specific transaction codes or modules related to the error for more detailed troubleshooting steps.
