Let say i have this dataset
Field1 Field2 Field3
123456 A12345 AA1234
222345 AA2234
AA3234
What I want to create are new column based on the value in the specific field, like if Field1 contain value and Field2 contain value and Field3 contain value then Field1 value, then if Field2 and Field3 then Field2 value. Lastly, if Field3 then Field3 value.What is the best practice to create the workflow.
