snc -> pi -> informatice

Hi All,

I have received a new requirement where the data comes from SNC to PI to Informatica System.Thy have provided two XML structure as below:

ProductActivityNotification_In XML

ProductForecastNotification_Out XML

SNC to PI is through RFC Call.Right now,I have only this much Information.I have 2 questions on this:

1]     How do I connect to Informtica?I mean which adapter we use?

2]     How will i make use of the above mentioned XML Structure?Should i need to import them to PI as External Definition?

Thanks,
Sahana
