Recover an ABAP Program or FM

What if you accidentally delete a custom program/ function module:

Program:

Go to Tr: SE38

Type in your program name same as earlier name-> save and activate the empty program -> go back to the SE 38-> Go to Utilities -> Version management -> Check the recent version than your current one -> Retrieve.

Function Module: Tr: SE37

Type in your FM name same as your deleted one-> save it to the same function group as before without any code-> come back to the SE37-> Go to Utilities -> Recover your old version.

This methodology is strictly recommended for transportable objects only.
