Purpose: Download all Function Module source code belonging to a Function Group to local file system
Usage Scenario:
– you are working a new function group which doesn’t have a version history and you want to take a backup of the source code
– backup source code in between releasing the code
Please note that the following code will only download FM. Feel free to extend or modify the code to your needs.

Unless I am very much mistaken, you want to be able to take a copy of a function module, and then upload it again at a later date.
If this is the case, I would advise you to look up SAPLINK, where you can save any type of SAP object on your local drive.
I am really lazy, so whenevr I have a problem to solve I look up the internet to see if anyone has solved it before me. I think that is what the “design patterns” business is all about also.
If I have misread your intent I aplogise, otherwise I hope you can benefit from this wonderful open source tool.

Hi Paul,
I have never used SAPLink and I will check it out. Thank you for pointing it out to me. I appreciate it.
I wrote the program above as a tool to help to take a backup of the code during programming so it helps me refer to capture older version of the code that cannot be captured in version history. Usually I just take a backup of the current code, modify the code and I will use the backup to refer to the old code before releasing the change in a transport. With a new FM, the original code is not available in version history since the object has not been released.
I will have a look at SAPLink if it has similar feature or even more features that can assist me with day-to-day task in writing code.
Thanks,
Stev
