Adjustment Category: Without Modification Assistant 
To adjust objects without the Modification Assistant, use version management wherever possible (see
Version Management of Repository Objects). When modifying objects where version management cannot be used, carefully document any changes that you make. This documentation can be of great assistance the next time the object needs to be adjusted. Choose Change from the maintenance transactions of the individual ABAP Workbench tools to adjust objects without the Modification Assistant.
