SAP BW System Copy: Resolving RFC Inconsistencies and Transport Errors in Parallel ECC/BW Copies
Sara Kim breaks down the critical post-copy cleanup most basis teams skip—and how to fix it with standard tools and a bit of ABAP
You’ve just finished copying your production BW system to the pre-production landscape, everything looks green in SWPM, and you’re ready to hand it over. Then the tickets start: transports are landing in production by mistake, a critical process chain pulls data from the wrong ECC client, and an Open Hub destination is silently failing. I’ve seen this script play out in half a dozen large SAP landscapes, and it almost always comes down to three things: sequence, logical system names, and lingering production metadata.
When you’re copying BW and the connected ECC system in parallel, you’re not moving isolated containers. You’re cloning a web of RFC destinations, source system assignments, and transport routing rules. Miss a single cleanup step, and your pre-production environment behaves like it’s still production—often with expensive consequences.
The Real Story
The core issue isn’t the database copy. Tools like SWPM (for homogeneous system copy) and RSCOPY (for BW‑specific post‑processing) handle the heavy lifting. The pain starts when teams treat the process as a one‑and‑done operation.
In a parallel copy scenario, where both BW and ECC are refreshed at roughly the same time, you’ll hit problems if the sequence isn’t respected. If you copy BW first, its RFC destinations still point to the old ECC system. If you copy ECC first and then BW, the BW source system assignments in table RSBASIDOC still reference the production ECC logical system. Either way, once the systems are up, process chains and DTPs will try to connect to the wrong place. Simultaneously, development objects in table TADIR retain production system identifiers, so the transport landscape tries to import changes into production when you’re testing in pre‑prod.
