Warning: the following job steps cannot be reached with the current job step flow logic

If you get this error, I would guess that you have somehow set another step instead of the first one as the starting step in the package. 

To solve this problem:

• Right click on the Jjob and select "Properties"
• Click on the "Steps" option
• Below the Job list, see the "Start step" option, verify the step showed is the first one
• Click the Ok button so save any modifications
