Hold Data in Module Pool Programmin

This is my second post of the day. I am working on Module Pool and came across Hold Data option to retrieve back the values entered on screen when you come back to the same screen(this is screen specific).

How to do it..

Go to scr attributes and check the hold data option.

Now in the menu ,Go to System-->User Profile-->Hold Data.

You will get a message saying 'No field was held'. Jus ignore tat msg.

Now when u run the transaction, enter the values, process it. When u cum back to d same screen, the values u jus entered comes as default values.

But there is a catch....this method retrieves only those field values whose fields have dictionary reference.
