This page explains why SAP requires a Plant to be assigned to a Distribution Chain for anyone working with S4HANA Sales and Logistics. In short, this link tells SAP which commercial pathway a warehouse is allowed to serve. It matters because availability checks, delivery creation, stock allocation, and pricing behaviour all depend on this assignment. Use it when you want materials to flow cleanly from storage to customers, and avoid skipping it unless you enjoy delivery blocks that feel personal.
</aside>
This is the configuration that tells SAP which combinations of Sales Organisation and Distribution Channel a Plant is permitted to supply. A Plant does not automatically serve every sales route. It needs to be declared as part of a Distribution Chain, or SAP simply shrugs and pretends your warehouse doesn’t exist.
This assignment is the bridge between logistics and commercial intent. Without it, the left hand (Sales) wants to sell things the right hand (Logistics) isn’t allowed to ship.
SAP separates where goods are stored (the Plant) from how goods reach customers (the Distribution Chain).
A Plant can only participate in a sales flow if it is explicitly assigned to that Distribution Chain.
No assignment means no deliveries, no ATP, and a sales order that refuses to acknowledge the warehouse’s existence.
The rule is simple:
If Sales and Logistics aren’t formally introduced, they don’t talk to each other.
Plant
A physical location where materials are stored, produced, or shipped.
Distribution Chain
A combination of Sales Organisation + Distribution Channel. It defines a commercial route to market.
Assignment
The formal relationship that tells SAP a Plant is authorised to fulfil that commercial route.
