How To Pass Multiple Line Items Data Between Web Dynpro Java Callable Objects in GP

[former_member4529]

Recently I was working on developing a GP process using Web Dynpro Java callable object where I need to pass table data (multiple line items) from one callable object to another using GP parameter mapping. After stumbling over the issue for quite some time finally I got the solution how to do this. But seeing the lack of documentation on this part in SDN indulged me to write a weblog which I hope may help many other developers like me.

The scenario is like this :
We have two Web Dynpro (GP Interface) callable objects.
