Scenario 2:

When importing support packages by SPAM/SAINT, the process stops at 'IMPORT_PROPER' phase with the following error.

The import was stopped, since an error occurred during the phase

without your input. 

After you have corrected the cause of the error, continue with the 
import by choosing Support Package -> Import queue from the initial 
screen of the Support Package Manager. 

The following details help you to analyze the problem: 

- Error in phase: IMPORT_PROPER

- Reason for error: TP_STEP_FAILURE

- Return code: 0014
