My workflow consists of the following:
1. Read individual Sales Transactions for the year 2018, summarize and write the Yearly total by Sales person to separate output file
2. Read individual Sales Transactions for the year 2019, summarize and write the Yearly total by Sales person to separate output file
3. Read the yearly total for 2018 and 2019, and write the comparison up or down into output file.
Can I have Input parameter, say Run type with Options "Run Step 1 only", "Run Step 1-3", based on which either run or suppress the steps
