Update allocation structure in a created settlement role

Hello All,

We want to change settlement cost element in allocation structure from "By cost element" to an (internal settlement cost element ). for CTR.

Because, we cannot change current settings in the allocation structure

- So, we've created a new settlement profile with a new allocation and assigned it to process order type.

*when creating a new order, the settlement role catches the new settlement profile and that is OK.

*but, if we try to settle an old order that already created before, and by activating flow trace we found that; it gets the old settlement profile, and not the new one ??

kindly advice,

Can we update settlement role in the order to catch the new settings (settlement profile)?

Thanks,

Ibrahim
