Which effective pricing date in order repricing in case of different values in lines ?

Dear all,

I'm woundering which date is used during the order repricing (R42750) to retrieve the relevant adjustment in case of multiple values (SDPEFJ) of effective pricing date in the order lines ?

(in the line repricing , you can choose your date in PO R42950 but I haven't found out this kind of possibility in R42750)

Thanks
