Retrieving older version of sapscript

As you may have come across, there is no versioning available for sapscript in SAP (at least until SAP ECC6, no idea if newer one has it). So is there a way to retrieve your old version?

Simple and straight answer will be, NO!

Workaround? Probably there is. Here is what I've done to work around this:

1. Use SE03 to find the the last good transport for the sapscript.

2. Use STMS_IMPORT to import the previous transport into your QA or Sandbox.
2.1 Extras - Other Requests - Add
2.2 Put transport request, client and click on transport again.

3. Download the sapscript form using RSTXSCRP to your local PC.

Good luck!
