In the above case

No of Records:  4,452,847

No of Records for one File chunk: 500000

No of Chunks that can be created: ROUND (4452847/500000)= 9

Step 3: Create a Data Model with the above no of Chunks:


Step 4: Create a report based on the DM as below.


Step 5: Set the Report Properties:

Select Enable Bursting Name: Shipment burststep5

Step 6: Open the DM and create Bursting Steps:

Choose a name for Bursting Report (Shipment Burst)

Type: SQL Query

Data Source: DWH

Bursting Query:

Split By: /DATA_DS/G_1/HASH

Deliver By: /DATA_DS/G_1/HASH


Add the below query which will create 9 reports that uses Parameters as setup below.

step6_2Step 7: Schedule the report using the above DM and Report.

You could either schedule the report or run instantly.  No need to do any further setup in the scheduler.

step8Step 8: Observe the reports are available in the SFTP environment (Snowflake)
