Integrating SAP PI with Microsoft Navision and Microsoft XAL

Hello Experts,

I have a requirement to integrate SAP PI 7.31 (Single Stack) with Microsoft Navision (V3.10) and MS XAL systems.

Please let me know if anyone has worked on this and are there any adapters to connect to MS Navision and MS XAL?

This requirement is to process PO/SO between SAP ECC and MS Navision(V3.10) and MS XAL.
