Thanks for your reply Joao,
As I mentioned I want to know at least the details of one cycle between WM and Handheld device, for instance: Stock Transfer from storage bin to another storage bin.
We will use ABAP application on the handheld for that, but till now I didn't know what actually the roles for each one involved in this cycle !
As I mentioned one more time
"In Stock Transfer from storage bin to storage bin, from which screen we will create the TO (handheld screen or SAP TO screen), and what are the responsibilities of the handheld guy (what are the bar codes which must be scanned by handheld) ."
Can anyone describe the scenario for me ?! what are the steps in stock transfer must done on SAP system and what are the steps must done on Handheld.
Just a few description for this scenario.
