How serialized inventory is reserved
Before reserving serial, tracked, assembly, or kit class inventory to fulfill a part request auto-reservation ranks all the inventory in the supply location that could fulfill the request and reserves the most suitable item.
- Searches the first location for unreserved inventory plus inventory that was reserved for lower ranked part requests.
- If inventory is found, ranks inventory using the inventory ranking criteria and reserves the highest ranking inventory for the request.
- If no inventory can be reserved in the first location, searches the next location and repeats the ranking of inventory.
When auto-reservation ranks the available inventory for a new part request, inventory that's reserved for higher ranked part requests is not considered. This means that a higher ranked request can retain a reservation of lower ranked inventory even if a higher ranked inventory becomes available.
The following table provides an example of the order in which five inventory items with the same part number are ranked and reserved if no preferred locations are specified.
Ranked order | Location | Ownership | Condition | Shelf-life expiry | Received date | Created date |
---|---|---|---|---|---|---|
Inv B | Supply | Operator | RFI | 2018 May 10 | 2017 May 10 | 2017 May 10 |
Inv A | Supply | Operator | RFI | 2019 Jan 05 | 2018 Jan 05 | 2018 Jan 05 |
Inv D | Supply | Operator | INSPREQ | 2018 Apr 7 | 2017 Apr 7 | 2017 Apr 7 |
Inv C | Supply | Vendor | RFI | 2018 May 10 | 2017 Jan 10 | 2017 Jan 10 |
Inv E | Remote supplier | Operator | RFI | 2018 Mar 7 | 2017 Mar 7 | 2017 Mar 7 |
In the example below, you can see how preferred locations change the order in which the same five inventory items are reserved. Inventory A outranks inventory D, but a lower ranked inventory in a preferred location is reserved before a higher ranked inventory elsewhere.
Ranked order | Location | Ownership | Condition | Shelf-life expiry | Received date | Created date |
---|---|---|---|---|---|---|
Inv B | 1st Preferred | Operator | RFI | 2018 May 10 | 2017 May 10 | 2017 May 10 |
Inv D | 1st Preferred | Operator | INSPREQ | 2018 Apr 7 | 2017 Apr 7 | 2017 Apr 7 |
Inv A | 2nd Preferred | Operator | RFI | 2019 Jan 05 | 2018 Jan 05 | 2018 Jan 05 |
Inv C | Supply | Vendor | RFI | 2018 May 10 | 2017 Jan 10 | 2017 Jan 10 |
Inv E | Remote supplier | Operator | RFI | 2018 Mar 7 | 2017 Mar 7 | 2017 Mar 7 |
