Define Merge Actions for Business Object History Properties
Use the History page in the Business Object Properties window to define whether or not to overwrite the history tracking options for a Business Object.
Note: The Business Object Properties window is available in the
      
      Business
        Object Editor (accessed from within the 
      Object
        Manager in the 
      mApp Editor).
    
    Good to know:
- You can only configure separate merge actions for individual Business Object properties and areas if the Business Object is set to Merge in the Business Object Properties window (mApp page). If the Business Object is set to any other option, or if the Include in mApp check box is cleared, then you cannot configure separate merge actions for individual properties or areas.
 - For more information about defining history properties for a Business Object, refer to Define History Properties for a Business Object.
