  SAP Error Message:
  
  VHU01127: If you undo "Maintain &1 manually", &2 are overwritten
  
  Explanation / Cause
  This message typically appears in the context of SAP Vehicle Management (VHU) or similar modules where certain data maintenance steps are performed manually. The message warns that if you undo a manual maintenance action (denoted by &1), then certain related data or objects (denoted by &2) will be overwritten.
  In other words:  
  
  You have manually maintained or changed some data (e.g., vehicle master data, inspection data, or related configuration).  
  Undoing this manual maintenance will cause the system to overwrite or reset related data fields or objects.  
  This is a safeguard message to alert you that undoing manual changes is not a simple revert but will trigger overwriting of dependent data.
  
  
  Typical Scenario
  
  You manually maintain a certain data set or configuration (e.g., vehicle data, inspection results, or maintenance instructions).  
  Later, you decide to undo this manual maintenance (e.g., revert to system-generated or default values).  
  The system warns that undoing this manual maintenance will overwrite other related data, potentially losing manual changes or updates.
  
  
  Solution / How to Handle
  
  
  Understand the Impact:
  
  Before undoing manual maintenance, understand which data (&2) will be overwritten. This might include vehicle data, inspection results, or other dependent records.
  
  
  Backup Data:
  
  If possible, back up or document the current manually maintained data before undoing it.
  
  
  Confirm Undo Action:
  
  Only proceed with undoing manual maintenance if you are sure that overwriting the related data is acceptable.
  
  
  Perform Undo via Correct Transaction:
  
  Use the appropriate SAP transaction or function module designed to undo manual maintenance. This ensures that the system correctly handles the overwriting process.
  
  
  Reapply Manual Changes if Needed:
  
  After undoing, if some manual changes are still required, reapply them carefully.
