Hi,
Considering this control is getting executed by Mainframe JCL:
Step: 1
Make sure you have two separate control point created one for "Go" scenario where you will have all three extracts to extract data from 3 files.
The other control point created one for "No Go" scenario where you will have all two extracts to extract data from 2 files.
Step: 2
In the JCL create two steps, in first step try to execute Control Point related to "Go" scenario unique Schedule ID (Example: Schedule ID 1)
In second step try to execute Control Point related to "No Go" scenario unique Schedule ID (Example: Schedule ID 2)
Hope this will be helpful!!
