Level 3 assignment 2 performer - dont understand

@Ibra
Here there are two different work flows one is dispatcher and the second is performer.
in dispatcher in_transactionitem or out_transactionitem will be string. when we upload to queue items data type will be changed to queueitem and stored in queues. when we use GetTransaction Item activity in performer output will be queueItem data type. you are getting confused between dispatcher and performer. hope this will help you. create as two processes dispatcher and performer.
