If I had a field named "type of fruit" with a value of "apple" ( to correlate to a field named of the same name "apple" on another list named "fruits") is there a way to use the aforementioned value of "type of fruit" to dynamically "set the field" in "value assignment" and update the field of the same name as the value of "type of fruit" on another list with a value of let's say "true"?
Yes, you can update a list item on another list based on a field value on the current list as the following.
- Open your workflow via SharePoint Designer.
- In your workflow Stage/Step based on your workflow platform 2010 /2013 > Add an action called
Update List Itembelow
- Now click on this list to specify the list that you need to update its field. (In your case it's Fruit).
Update list Itemdialog specify your list (In your case it's Fruit).
- Click add to specify the field that you need to set its value with a value from your current list item.
Find List Itemsection, you should find the relation between your first list to another (fruit). (in your case, you don't have ID relationship, you just has Type of Fruit in the first list and Fruit name in the second list. So you should specify the field that holds the fruit name in the second list (Fruit) with the value of a type of Fruit in the current item.
