Short, descriptive — shown in the warning/block dialog at export time.
More trigger points (e.g. on Save, on Refresh) will be added later.
Disabled rules stay in the list but never fire.
Each line is a value of the grouping attribute that's intentionally non-identical across rows. Add a Usage here once you've reviewed it and confirmed the duplication is by design.
When this rule blocks an export, each grouped row in the modal becomes click-to-expand — revealing every instance underneath it with the full attribute spectrum so you can spot exactly what differs. Recommended for group conflict rules; harmless to turn off if you only care about the summary.
group conflict
Tip: contains — Attribute=Itemcode, Value=?? blocks any export with unresolved colour codes. group conflict — Attribute=Usage, Must agree on=Itemcode flags any two rows sharing the same Usage but tagged with different Itemcodes (likely mislabelled).
