6) What is the purpose of the inspector activity?
Ans : The Inspector activity is used to write the output of any or all activities and process variables to a file and/or stdout. This is particularly useful when debugging process definitions and you wish to see the entire schema instead of mapping specific elements to the Write File activity.

7) What are the process variables that are available to all activities as inputs?
Ans : Global variables and process context.
8) How the file poller activity does works.
Ans : This is a starter activity which starts the process whenever there is update for the file that is specified.

9) What are break points?
Ans : Break points are used to check the inputs and outputs of each activity during testing the design so that we can debug our design. We can place the check points for all activities on input and output side.

Ans : The encoding techniques in WSDL Encoded and literal.

11) What are the different variables in BW?

16) What is sub process and what is its use?
Ans : Whenever we call a process from another process, the called process becomes the sub process. Sub process helps in reducing the complexity of the design by assigning the activity in other process.
