Hi All - 

We have a requirement to auto populate Ship to location at PO line level based on the Ship to location selected at PO Header level. Below are the step involved in this requirement: -

1. User edits an existing PO
2. Change the Ship to location at PO header level
3. Based on Ship to location selected at PO header level, auto populate the Ship to location on all PO lines
4. Auto population should trigger when user clicks on Submit button
