Stop Losing Days to a SQL Syntax Error: The Sybase ASE SAP System Copy Trap

David Thompson breaks down what you need to know before your next system refresh turns into a multi-day debugging session

I’ve spent two decades watching enterprise projects stumble—not over grand architectural failures, but over tiny, forgotten details that someone could have checked in ten minutes. This is one of those details. If you’re about to run a heterogeneous or even a homogeneous SAP system copy with Sybase ASE as the target database, there’s a baked-in syntax landmine waiting to blow up your import phase. And here’s the maddening part: the fix has been sitting in an SAP Note for years, yet teams still treat it as a surprise every time.

The Real Story

The technical surface is simple. During a system copy, SAP’s R3load utility exports database content into platform-independent SQL files. Those files are then replayed against the target database. The problem: the export routine includes GO batch separators—a construct Sybase ASE simply doesn’t understand. When you feed that file into your shiny new Sybase ASE instance, the import fails with a cryptic SQL syntax error, and your careful weekend maintenance window starts collapsing.

Most engineers then dive into the usual suspects: network glitches, invalid table structures, buffer sizes, Unicode conversions. I’ve seen Basis teams burn 20+ consultant-hours chasing shadows before someone remembers to check SAP Note 1738258. The note explicitly states that the pre-generated SQL files contain unsupported syntax, and it provides two paths to resolution: either manually strip out the GO lines with a provided script, or regenerate the export using corrected R3load parameters that suppress batch separators in the first place.

This isn’t a migration complexity issue. It’s not a sign of a fragile Sybase platform. It’s a known product quirk—one that keeps tripping up even senior architects who’ve done a dozen system copies but never happened to target Sybase ASE before.

What This Means for You

If you’re a Basis administrator, this error will hit you when you least want it: at 2 a.m. on a Saturday, with the business expecting a ready sandbox by Monday morning. Your instinct will be to restore from backup and retry with different R3load flags, none of which will work. Without the note, you’re debugging blind.

If you’re a technical consultant or project lead, the cost isn’t just time. It’s the erosion of stakeholder confidence. When a “standard” system copy fails, executives start questioning whether the entire target architecture—Sybase ASE, cloud infrastructure, the new ERP version—is fundamentally unsound. I’ve seen steering committees demand a rollback to Oracle just because a 10-line SQL fix wasn’t applied. That’s an expensive overreaction.

Even architects designing hybrid landscapes (think SAP SuccessFactors integration with on-premise SAP ECC on Sybase) get caught. A clean system copy is often the first deliverable that proves the design works; a syntax error on Day 1 undermines that narrative before you’ve even started loading data.

The good news: the correction itself is trivial. SAP Note 1738258 describes both an in-place fix (a Python or ABAP script that removes GO from every export file) and a prevention measure (regenerating exports with R3load’s -nogo or equivalent parameter, depending on your release). The note even walks you through verifying that the import will succeed before you commit the full runtime.

Action Items

Here’s what you need to do—ideally during your planning phase, not during the outage:

• Pull SAP Note 1738258 before you start the export. Don’t assume it’s already been patched in your support package stack. I’ve seen instances where the export tools were current, but the procedure still defaulted to batch separators.
• Check whether you’re using pre-generated SQL files. Homogeneous system copies often recycle the same export set; if that export was created without the -nogo switch, every target Sybase ASE will choke.
• Apply the fix that fits your timeline. If you can’t re-export (e.g., the source system is already decommissioned), use the manual cleanup script. Otherwise, regenerate with corrected R3load parameters—cleaner and repeatable.
• Test with a single small table first. Pick something like USR02 or T000. If the import of that one table succeeds, your entire run will, too. That ten-minute sanity check saves hours of uncertainty.

Community Perspective

On forums and in SAP user groups, the mood around Note 1738258 is a mix of relief and frustration. Basis engineers who’ve been burned once often add a step to their runbooks: *“if target is Sybase, check and strip GO statements.”
