Adjusting Enhancements After an Upgrade 

You can adjust an enhancement of a Web Dynpro ABAP object after an upgrade using the Adjustment Tools of the Enhancement Builder. Usually no other actions are required, but if an enhanced component is changed in the original system and the change is imported into the system where the enhancement is, this could lead to a conflict. The following types of conflict are possible:

●      Name collision

●      Reference to an element deleted in the original system

The adjustment tool has specific functions to handle each type of conflict:

●      Name collisions: Functions for renaming or deleting names

●      Reference to a deleted (parent) object: Function for deleting object

The adjustment tool also enables you to compare the original component at the time of enhancement to the newly imported version.
