Hello,

• Open your Zoho Inventory organization.
  

• Navigate to Settings using the gear icon from the top-right corner.
  

• Select Automation from the sidebar. Now click on the button adjacent to +New Workflow Rule.
  

• Out of the four options from the drop-down, select Custom Functions.
  

• Now let's add a name to this workflow rule and make sure that there are no spaces between words.
  

• Select Purchase Orders against module.
  

• Add a description if you need one.
  

• Now, the workflow type is going to be Event Based.
  

• The condition to set shall be, "When a Purchase Order is" "Created or Edited".
  

• Function shall be executed "When any field is updated".
  

• And set the frequency of execution to "Everytime".
  

• Next, you are required to set two triggers that can execute this custom function. You can do so by clicking on the Apply Advanced Filter option below the workflow condition.
  

• Trigger 1: "When" the "Purchase Receive Status" "is" "Partially Received".
  

• Trigger 2: "Or" when the "Purchase Receive Status" "is" "Received". 
  

• Now copy and paste this code snippet into the deluge pane:
  

purchaseorderID = purchaseorder.get("purchaseorder_id");

• Don't forget to navigate to the line containing the authtoken within the code snippet and replace the XXXXXXXXXXX with the auth token number that you had generated in the first step.
  

• To send this notification to one or more dedicated email addresses instead of the vendor, you can do that by navigating to this line:
  

• to : vendoremail //EMAIL ID
  

• And replace vendoremail with one or more email addresses of your choice like "abc@xyz.com, def@xyz.com"
  

• Hit Save to finish.
