Adding additional Fucntions in QP_CUSTOM_SOURCE

Hi all,

I am using the QP_CUSTOM_SOURCE to map the attributes manually and send them into the pricing engine instead of doing it through Attribute mapping method.

I have two questions when I try to add the logic in QP_CUSTOM_SOURCE.

1. Can I call the my custom PL/SQL package which I created separatly from QP_CUSTOM_SOURCE?

2. Can add additional functions and procedures with in the QP_CUSTOM_SOURCE package itself and call those function names from Get_Custom_Attribute_Values method?

I have no idea what Oracle is suggesting. Please confirm me the possibiliities.

Thanks
