From a lot record, Bonx displays traceability in two directions:
  • Upstream: materials, receivings, suppliers and manufacturing orders that produced the lot.
  • Downstream: manufactured lots, shipments and customers that received the product.
Bonx builds this graph on demand from completed stock movements. There is no separate traceability table to maintain.

​
Building the chain

The link between a material and a product goes through the manufacturing order or the transformation order. Lots consumed and produced by the same order are linked even when the declarations were made at different times. The chain includes:
  • receivings and purchase orders upstream;
  • manufacturing and transformation orders, including several levels;
  • shipments and sales orders downstream;
  • the inbound or outbound side of an inter-site transfer.
A reversed task no longer appears in the graph.

​
Supplier lot number

At receiving, enter the supplier number as the lot name. Two receivings with the same name, article and location feed the same lot and therefore share one history. If a supplier reuses a number, add a suffix to keep the lots separate.

​
Reading the graph

Each node represents a lot or document. Each link shows the related movements, quantities and dates. Bonx walks up to 10 levels of manufacturing and transformation upstream and downstream. It reports a truncated result when this limit is reached. The graph shows which lots are linked. It does not calculate the exact share of each material in each finished product when an order consumes or produces several lots.

​
Current limitations

  • An inter-site transfer ends the chain. Run the search again on the destination site’s lot.
  • Lot splits and merges do not preserve provenance.
  • Corrections, inventories and scrap do not create traceability links.
  • A produced lot’s expiry date is not calculated from its components.
  • The graph does not yet have a printable export.
