Hi @mjliu 

Your Start Event is the NAC Form.

Are you taking a single item or record value or multiple items / records from a Repeating Section ?
Which is the “Keyword” field - eg EmployeeID, DepartmentName 

If you have a single item and the unique column field is called Department and the value on the form is “Engineering”

1. Query a List. Condition → When Department, equals, Start Event: Department field value
   Output: SPO_Department   (Important)

   

2. Branch by Condition
   SPO_Department → Number of Items return
   0 means No such item exists, so you can Add
   1 or more means that there are existing items with that keyword

   

final workflow

If you have a multiple items , Repeating Section is called RS and and the unique column field is called Department and the value on the form is “Engineering”

1. Loop For Each. Target collection is “RS”
2. Query a List. Condition → When Department, equals, Loop for each-Current item-Department 

   

   

   Output: SPO_Department   (Important)
3. Branch by Condition
   SPO_Department → Number of Items return
   0 means No such item exists, so you can Add
   1 or more means that there are existing items with that keyword

   

Final workflow - Multiple Items
