PO to AP DFF info transfer

We have setup DFF on PO lines. As I have read in guides, if we want to transfer DFF info from PO to AP then it has to done on PO distribution line DFF.

1) Can we transfer info from PO lines to AP lines or to AP distribution line?

2) if it is not possible, then is there a way to transfer PO Line DFF to PO distribution line DFF?

 

Your help will be highly appreciated.

 

Thanks
