Copy Object Changes 
From the task list, you can call the Start Retrofit task to copy changes that you have made in a development or maintenance system to another system.
You have made a change or correction in your development or maintenance system.
You have created a change request for your changes and released it so that it appears in the list of requests for changes to be copied.
In the task list, choose Start Retrofit.
The Select Transport Request in Retrofit System dialog box appears.
In the dialog box, select your change request or task and confirm by choosing Continue.
The Confirm Changes dialog box appears, containing a list of all changed repository objects.
Note
A traffic light symbol indicates whether or not the system can copy the change automatically. You can find more information about the traffic light icons under Confirm Changes.
Caution
A green traffic light does not mean that the system can copy the changes completely. If the starting status is different in the source system and the target system, the green traffic light does not guarantee that copying the changes will result in a program that is syntactically and semantically correct. You need to check the accuracy of the program yourself after copying the changes. This is your responsibility.
Note the detailed change display (Merge-Editor) and the messages displayed for the object.
To access the detailed change display for an object, click on the object name in question.
Note
If necessary, you can make manual adjustments to source code changes here (see Splitscreen Editor). This type of adjustment is not possible for non-source code type repository objects (such as function modules).
If you want to copy the changes, select all objects to be changed that have either a green traffic light (complete copy possible) or a yellow one (limited copy possible) and confirm the dialog with the list of objects to be changed.
Caution
The system only changes objects that you have selected.
At first, the system saves the changed objects as inactive versions in the database.
The Inactive Objects Belonging to <BENUTZERNAME> dialog box appears.
Activate the changed objects and confirm by choosing Continue.
The system checks the syntax in the changed objects. If it finds any syntax errors, the system cancels activation.
Confirm the syntax check.
The Retrofit Status Query dialog box appears.
Choose Yes, No or Cancel.
With a traffic light display, the system creates a log of the status of the change copy and the retrofit in the task list..
You can now test the semantic and syntactical accuracy of the change that you have copied in the target system. If you do not find any errors, you can release the change request that you created before in your retrofit system’s task list.
