Why your SAP data is inaccurate — and it's not SAP's fault.

Every time someone tells me "our SAP data is a mess," I ask a few questions, and almost every single time, the answer has nothing to do with SAP. The system did exactly what it was told, exactly when it was told. If the number on screen doesn't match what's actually on the shelf, something happened on the floor that never made it into the system — or it made it in late, or someone found a shortcut because doing it properly during a busy shift felt like a luxury nobody had time for.

Picture this: the shelf says 40. SAP says 42. Nobody's lying — the count on screen is just repeating something that was entered wrong, or late, or never corrected.

I've seen the same handful of patterns show up again and again, at different sites, with completely different teams.

Someone unloads a truck, and the goods receipt doesn't get posted until hours later because paperwork felt like it could wait until things calmed down. By the time it's finally entered, nobody actually remembers if it was 40 units or 42 — so whatever gets typed in is really just a best guess dressed up as data.

Or transactions get batched at the end of a shift instead of logged as they happen. The timestamps look fine, but the actual sequence of events is gone, which means when something doesn't match later, there's no way to trace back what caused it.

Or someone just overrides the number to make it "correct" for now, without asking why it was wrong in the first place. That fixes the symptom for exactly one day. The actual cause is still sitting there, waiting to cause the same problem next week.

And honestly, a lot of training doesn't help either — people get taught which buttons to press, but nobody explains why the timing or the order of steps actually matters. So they follow the steps, but they have no idea what breaks the moment one gets skipped.

None of this ever shows up as a system error. It just shows up as "SAP's wrong again," which is usually the one explanation that isn't actually true.

The fix is almost never a system change. It's a behavior change — closing the gap between the moment something physically happens and the moment it gets recorded, and making the right way to log it the easy way instead of the slow one.

If your numbers keep drifting from reality, the system isn't lying to you. It's just repeating exactly what it was told.
