Once a PF has been split into two or more batches, you get several FPs: PF001; PF002, etc.
On the transaction view, once the two FPs have been recorded on the item view, a window offers you to choose the FP to be displayed (PF001, PF002...).
In this window, a button allows you to validate all the FPs at once. In the case where all the FPs cannot be validated, the button cannot be clicked. When the mouse passes over it, a tooltip explains the reason.
