SAP Transfer Pricing for Services

Dear Experts,

We have activated Profit center transfer pricing and it is working fine for the exchange of goods from one profit center to another profit center through Stock Transfer Order(STO), but we are facing issue in managing with services rendered from one profit center to another profit center with markup value(services like, application services/maintenance services/travel services etc). Here services are being rendered from one profit center(plant) to another profit center(plant).

Please advice me, how can i map service scenario with profit center transfer pricing.

Regards,

Sam
