Hi,
According to the problem you described, it seems that the approval status of your purchase order is not Approved, so you can't click the Purchase Enquiry button, which means that the purchase order is not in a status that allows for inquiry. Perhaps you need to change the information in the Purchase order lines to change the purchase order from Confirmed to Approved, so that the Purchase Genuine button is enabled.
As described in the documentation:



To enable the Purchase Enquiry button in Dynamics 365 after creating a purchase order and adding lines to it, you can follow these steps:
- Open the purchase order you created.
- Verify that all required fields are filled out correctly, such as vendor, items, quantities, and prices.
- Make sure the purchase order is in a status that allows for inquiry. For example, if the purchase order is still in a draft or pending status, you may need to submit or approve it first.
- Check if there are any workflow rules or business process flows associated with purchase orders that may prevent the Purchase Enquiry button from being enabled. Ensure that these processes are completed or that any required actions have been taken.
- If the above steps do not resolve the issue, check the security roles and permissions assigned to your user account. Ensure that you have the necessary privileges to access the Purchase Enquiry functionality.
- If needed, consult with your system administrator or IT support team to ensure that there are no customizations or configurations that are preventing the button from being enabled.
By following these steps, you should be able to enable the Purchase Enquiry button in Dynamics 365 after creating a purchase order.
Best regards,
Kevin
