Priority and quantity merging

Priority decides which applicable price list supplies a product price when more than one list matches. Higher-priority lists are considered before lower-priority lists.

The Merge pricelist qtys setting changes what happens across quantity thresholds:

• When enabled, applicable lists can contribute quantity rows.
• When disabled, rows from lower-priority lists are ignored.
• Lists tied at the highest priority can still combine their quantity rows.

Within the resulting rows, the closest eligible quantity threshold applies. For a requested quantity of 24, a threshold of 10 applies before a threshold of 1, while a threshold of 50 is not eligible.

Example

An assigned contract list has priority 20 and a quantity-1 price. A dealer list has priority 10 and a quantity-50 price. With merging enabled, the dealer list may supply the quantity-50 row. With merging disabled, only the contract list contributes because it has higher priority.

Test overlaps with the exact quantities customers order. A list-priority check at quantity 1 does not prove that quantity 50 resolves the same way.

After Price Lists supplies its candidate, the shared Pricesystem selection rule decides how that candidate competes with other Magento and Pricesystem price types.
