Most SAP teams know about retrofit. Fewer know there are two types – and the difference matters most during a RISE migration.
Technical retrofit carries a change between environments that share the same codebase – reliable and well-understood. But when ECC and S/4HANA run in parallel, the codebases differ. Moving the original transport into S/4HANA could introduce incompatible code or unnecessary customization.
What needs to carry over isn't the code. It's the business requirement behind it.
See how Rev-Trac's functional retrofit capability handles this by cloning the business requirement into the S/4HANA landscape, removing incompatible transports and updating the delivery strategy automatically.

Most SAP teams know one type of retrofit in SAP. There are two and the one you're missing could be the gap that hits you at go-live.
