How to Pass the values from the Process to Business Object

Process studio defined end to end process for back office. Process  will create with the use of business Object.
I  have already Created the Business Object for the addition of  two numbers.But in this object we are passing the values by assigning the values to the Data Item defined in Business Object.

If we have to pass the values from the process to Object then we have to define two blank parameters on the start stage of  business Object.
Open the start Properties window and define two inputs. We have defined "A" and "B" variable which will be use by Process Object to assign the values and These values will be stored in the "a" and "b" data item.(Refer "Store In" Column in below screenshot) .Click on OK button .

Please make sure that these "a" and "b" data item should be blank at Business Object level.



Now you can see in below screenshot all three data Item have null value. These three data items will get the value from the Process.

Save the Object.







 Now Create the Process by selection the Create Process Option





Provide the name of the process and click on Next button. Then on the next window click on Finish button without entering the Description.
