Go to Grower > Confirm POs.

 Use filters to Search for the purchase order needed.

 Once the PO has been found, go to the "Actions" column. Click on the drop-down menu and select the option "Substitute Item".

 The Edit Item tab will appear. Click on Downgrade Product. Notice that in this example, we are going to downgrade the product Pisa 45cm Green to Pisa 20cm Green Leucadendrum.

The Downgrade Product window will be displayed. Enter the product name (which must exist in the system with its corresponding name). Click on Save to finish. 

The confirmation message will appear at the bottom right corner of the screen.

 Notice that the product is now "Pisa 20cm Green Leucadendrum".

• Once a PO item has been downgraded and then that PO item is canceled, postpone or its quantity is reduced, the downgraded product will return to the original product line (before the downgrade process). This implies that the downgraded product line may not be used in another prebook or PO.
• It will not be possible to delete the original PO product line until all the PO lines downgraded associated to it have been deleted.
