RP3 flag in F0411 for logged voucher

There are two payitems in XYZ logged voucher in F0411

payitem 001 has RP3 flag as = P Amount = 100

payitem 002 has PR3 flas as - R Amount = 10

when we check P042002 application and search for logged voucher XYZ

we could see Gross amount as 100

Now From Row -> Redistribute PO ->

header shows Gross amount as 110.

ideally this should also show 100 since we only need to redistribute 100 and RP3 flag is P only for payitem 001

i want to understand is it possible to populate 100 as gross amount ?
