Consider Your Sourcing Hierarchy and Assignment Set Hierarchy
You use the hierarchy in your assignment set to tell Global Order Promising how to identify the sourcing rule that it should use to source your item.
The sourcing hierarchy is a detailed-to-general hierarchy. Each level of the hierarchy includes an assignment level and rule type. You can use the sourcing hierarchy to identify the sourcing rule, bill of distribution, or set of the item's attribute values that Promising uses to find a source for a combination of the:
- Assignment set, and
- Date, and
- Organization, and
- Item
Note
- Promising associates the sourcing rules in your assignment set with one row in the sourcing hierarchy.
- The values in the sourcing assignment, such as the item, determine which of the rules, bills, and set of item attributes that Promising will use when it searches your supply chain.
- More than one rule, bill, or set of item attributes might apply, so more than one row might apply. To identify the source for your item, Promising uses the rule, bill, or set of item attributes from the most detailed row in the hierarchy.
- Use the sourcing hierarchy to determine where your organization gets the item on x date. If Promising returns results that are different than what you expect, then you can search the sourcing hierarchy to identify the sourcing rule that Promising used.
To view the hierarchy, go to the Global Order Promising work area, click Tasks > Manage Assignment Sets, then click View Sourcing Hierarchy. For details, see Manage Promising Profiles.
Assignment Level Hierarchy
- Your assignment levels create a hierarchy in the assignment set.
- Promising uses the hierarchy to determine which sourcing rule to use when it searches the supply chain for a source for your item.
- Promising uses the most specific sourcing rule in the hierarchy first.
- The MSP_DEFAULT_ASSIGNMENT_SET profile option specifies the assignment set that Promising uses, by default. For details, see Manage Promising Profiles.
Assume your factory receives all items that are in the Fasteners item category from Supplier A. To source this, you can create a sourcing rule and an assignment set that:
- Buys from Supplier A
- At the Category assignment level
- For the Fastener item category
Six months later, you need to source the 10 Millimeter Screw Fastener from supplier B. To source this, you can create another sourcing rule and an assignment set that:
- Buys from Supplier B
- At the Item assignment level
- For the 10 Millimeter Screw Fastener item
The Item assignment level is more detailed than the Category level, so Promising sources the 10 Millimeter Screw Fastener from Supplier B, but still sources all other fasteners that are in the Fasteners item category from Supplier A.
Assignment Levels for Global Sourcing Rules
Here are the levels for your global sourcing rules, listed from the most specific in row 1, to the least specific in row 15.
| Specificity | Assignment Level | Assign the Sourcing Rule When | Applies for All |
|---|---|---|---|
| 1 | Item and Customer and Customer Site | The fulfillment line has the item, the customer, and the customer site that you specify on the assignment. |
|
| 2 | Item and Customer | The fulfillment line has the item and the customer that you specify on the sourcing assignment. |
|
| 3 | Item and Demand Class | The fulfillment line has the item, and the sourcing rule's demand class matches the demand class that you specify on the assignment. |
|
| 4 | Item and Region | The fulfillment line has the item and the region that you specify on the assignment. |
|
| 5 | Category and Customer and Customer Site | The fulfillment line has the customer and customer site that you specify on the assignment, and the Product Category on the fulfillment line matches the category that you specify on the assignment. |
|
| 6 | Category and Customer | The fulfillment line has the customer that you specify on the assignment, and the Product Category on the fulfillment line matches the category that you specify on the assignment. |
|
| 7 | Category and Demand Class | The Product Category on the fulfillment line matches the category that you specify on the assignment, and the sourcing rule's demand class matches the demand class that you specify on the assignment. |
|
| 8 | Item | The fulfillment has the item that you specify on the assignment. |
|
| 9 | Category and Region | The Product Category on the fulfillment line matches the category that you specify on the assignment, and the fulfillment line has the region that you specify on the assignment. |
|
| 10 | Category | The Product Category on the fulfillment line matches the category that you specify on the assignment. |
|
| 11 | Customer and Customer Site | The fulfillment line has the customer and the customer site that you specify on the assignment. |
|
| 12 | Customer | The fulfillment line has the customer that you specify on the assignment. |
|
| 13 | Demand Class | The sourcing rule's demand class matches the demand class that you specify on the assignment. |
|
| 14 | Region | The fulfillment line has the region that you specify on the assignment. |
|
| 15 | Global | The fulfillment line, sourcing rule, or assignment doesn't have to have any specific value. |

Here's another way to visualize it.
Assignment Levels for Local Sourcing Rules
Here are the levels for your local sourcing rules, listed from the most specific in row 1, to the least specific in row 15.
| Specificity | Assignment Level | Assign the Sourcing Rule When | Applies for All |
|---|---|---|---|
| 1 | Item and Organization | The fulfillment line has the item that you specify on the assignment, and the Organization on the sourcing rule matches the Item Organization on the fulfillment line. |
|
| 3 | Category and Organization | The Organization on the sourcing rule matches the Item Organization on the fulfillment line, and the Product Category on the fulfillment line matches the category that you specify on the assignment. |
|
| 3 | Organization | The fulfillment line has the organization that you specify on the assignment. |
