Document splitting when using online payment transfer in FM

Dear experts,

I use payment budget and want to transfer payments online. A prerequisite for this is to activate New G/L and document splitting by splitting characteristics KNBELNR and VOBELNR.

So when testing I saw that if I post an incoming invoice subject to VAT then when paying part of the amount with residual item, it is split between the two accounts - expenditure and VAT account.

Another thing is that if there are two items with different account assignments - when paying with residual item, the amount is split between the two items.

I've read in help that it works this way but is there any way to use online payment transfer without splitting in such a way the amount?

Thank you in advance,

Toni
