Inter-company transfer price calculation using advanced API

 Hi All, 

We have a requirement to calculate the transfer price using advanced API (MTL_INTERCOMPANY_INVOICES)  in inter-company transactions.

Here is the API hook (MTL_INTERCOMPANY_INVOICES.get_transfer_price).

Requirement: For certain Internal Sales order types, the transfer price needs to be calculated based on one user-defined "price list".

Please let us know how to write the logic in the API to get the transfer price.

This hook is called by the "Create Intercompany AR/AP Invoice" program (INCIAR/INCIAP).

Appreciate your help in advance.

Thanks,
