What it measures
% of warehouse transactions with errors
it measures transaction errors after they have occurred. The operational consequence, such as a picking error or inventory discrepancy, is already in motion before the KPI is calculated.
Business impact
- Higher 'chaos tax' from emergency cycle counts, wasted labour searching for 'lost' pallets, and production line stoppages waiting for materials the system showed as available.
- Corrupted inventory position data leads to phantom stock, breaking Available-to-Promise (ATP) commitments and forcing expensive last-minute production runs to cover the gaps.
Formula
(Error transactions / Total transactions) x 100Grain
One row per pick line confirmation — warehouse × material × employee × shift × date
Inside the Implementation Pack
A preview of what's actually built for this KPI — extracted from the real Implementation Pack, not a mockup.
This is the primary ratio the pack's other measures build on — trend, rank, and period-comparison variants, all on Fact_Warehouse_Picking_Line. It guards against missing dates and values with NOT ISBLANK checks.
Fact_Warehouse_Picking_Line— 9 mandatory columns — material key, warehouse key, ...Dim_Employee— key + nameDim_Material— material_key + material_descriptionDim_Shift— key + nameDim_Warehouse— key + nameDim_Date— Auto-generated calendar table — no customer data required
Full field-by-field data contract, in 4 SQL dialects (SQL Server, Snowflake, Databricks, BigQuery), ships in the pack.
| Target | 0.001 — performance considered compliant at or below this line |
| Warning | 0.005 — amber alert — triggers a review |
Both live in one Excel tab — change them, refresh the report, done. No DAX editing needed.
