• What is the cause and solution for SAP error message WY094 - Existing data will be overwritten ?

  SAP Error Message:
  
  WY094 - Existing data will be overwritten
  
  Cause:
  The message WY094 appears in SAP when you attempt to enter or save data in a transaction or application where data already exists for the same key or record. Essentially, SAP is warning you that the data you are about to save will overwrite existing data in the system.
  This message is typically encountered in scenarios such as:
  
  Maintaining master data (e.g., vendor, customer, material master) where an entry for the same key already exists.
  Entering or updating configuration or customizing data.
  Uploading or importing data where duplicates exist.
  Working with batch input or data migration tools.
  
  The system issues this warning to prevent unintentional data loss by overwriting existing entries without explicit confirmation.
  
  Solution:
  
  
  Review Existing Data:
  
  Before proceeding, check the existing data that will be overwritten. Verify if overwriting is intended and correct.
  
  
  Confirm Overwrite:
  
  If you are sure that the new data should replace the existing data, confirm the overwrite when prompted by the system.
  
  
  Modify Data Entry:
  
  If overwriting is not desired, change the key or data you are entering to avoid conflict with existing records.
  
  
  Backup Data:
  
  If possible, back up the existing data before overwriting, especially in critical master data or configuration.
  
  
  Check for Duplicates:
  
  Investigate why duplicate data exists. It might be necessary to clean up or merge records to avoid future conflicts.
  
  
  Use Proper Transaction or Tool:
  
  Ensure you are using the correct transaction or data maintenance tool that handles data updates properly.
