  1. Create a workflow that runs whenever an item in list 2 is created or updated.
  2. In this workflow, get the values of the quantity of the current item and the quantity of the corresponding Product from list 1.
  3. Add these values together.
  4. Update the value of the corresponding Product in List 1 with the new sum.

  • Use the SharePoint Designer Workflow activity "Set Workflow Variable", and in the value > Define Workflow Lookup screen, select your first list as the Data Source. The "Field from Source" should be the field that contains the value you want. In the "Find the List Item" section, you define WHICH item from the first list you want to use. Select "ID" in the field lookup, and in the Value lookup, use the Current Item's ProductName lookup. This tells SharePoint "Hey; lookup the value Quantity field in the Products list for the product I just selected in my new Customer Purchase record. Commented Mar 15, 2017 at 16:06
