Issues with Purchase Order Confirmations and Automatic Reservations in Advance Warehousing

Applies to Product –Dynamics 365 Supply Chain Management

What’s happening?

1. Purchase order confirmations are not visible for some POs after invoicing, and this issue is not replicated in lower environments.
2. Automatic reservation is not working for some selected items in Sales Orders, leading to work IDs not being created for those items.

1. This with purchase order confirmations may be related to customized code in the batch job regarding the Purchase Form, which affects the generation of confirmation journals for specific legal entities.
2. For the automatic reservation issue, it has been identified that items with no stock in the inventory are not being reserved automatically.

1. Check for any customizations in the batch job related to the Purchase Form.
2. Ensure that the reservation hierarchy is correctly set up for the items.
3. Verify that the item model group settings allow for automatic reservations and that the “Automatic reservation” option is enabled.
4. Review the warehouse management parameters to ensure that automatic reservations are configured correctly.
5. Confirm that stock is available in the correct warehouse and location.

1. Check the stock availability for the items in question, as physical reservations will only be shown for stocked items.
2. Review the reservation hierarchy and ensure it is set up correctly.
3. Validate the setup against the scenario to ensure that the configurations are appropriate for automatic reservations.
4. Investigate if there are any batch jobs related to reservations that might not be running as expected.
