Execution cannot be started when the Data Flow contains stand-alone steps.

Kaden B

Hello, I'm working on a data flow using Oracle Analytics Cloud through NetSuite Analytics Warehouse. Everything looks good in the data preview, but when I run the flow, I get the error "Execution cannot be started when the Data Flow contains stand-alone steps." There are no stand-alone steps in the flow, but I've narrowed it down to a problem with the join by trying a Save Data step after every step up to that point. Has anybody had this issue or know how to address it?

Hi @Kaden B ,

Instead of using the Branch step in your data flow, you should add your input dataset twice. In this way there will be no errors when you add a Join step.

Hi Kaden,

FYI, Below is the notes from MOS doc -

you must use two Data Sources instead of using a branch .

The way to do this without causing massive rework is to create a new Workbook / Data Set

and use it as the Data Source, multiple times as needed.

1) Create the new DataSet

2) Replace Branch with join of the DataSet_Columns and DataSet_Aggregate,

3) This WorkAround will prevent the error

4) Also using this method avoids re-creation of the same duplicated steps prior to the branch.

@Mallikarjuna Kuppauru-Oracle thank you for the quick response. Unfortunately I cannot access that document. It requires access to Oracle support, which I don't have.
