Transfer Price between different org with in the same OU - Custom hook

Hi Team,

In our project, we are having a the following requirement.

Client is having different mar up % for transferring the materials from one Organization to other organization.

We are using IR-ISO process to transfer the materials between 2 organizations.

In Transfer price we can give only fixed %. Hence, planned to use Transfer price list feature(attached at shipping networks). But Internal requisition transfer between 2 organizations of same operating Unit is not considering the Transfer price details.

In One of the Oracle notes(434377.1) mentioned that, We can achieve this through user define hook.

Can any one share us the the custom hool to achieve this?
