Teamcenter SOA Service : WorkFlow Submit And Complete with Form Attribute Modifcation

Problem statement :

1) Initiate the workflow 
2) Interact with workflow to provide the input
3) Complete the workflow
At the end of this section you will be able to deal with workflow related activities in Teamcenter

Visual of what we wanted through code ...

//One to One Relation between attachment and attachment types
//attachment type=1 //Target attachmetn
//attachment type=3 //Reference attachment
//Above statement says that last object defined in the item_uid string is attached in the workflow as //reference attachment
