Hello,

I am searching for some information on integration between SAP NW PI/PO with market cloud solutions and some content provider.

The cloud solution i am searching for are:

- CONCUR Online Travel Expense Management Software - Concur Hong Kong

And for content provider: Bloomberg or Reuters.

Are threre some standards for those?

Or could you help me to identify where to find the relevant information?

Thanks and best regards,

Vincent
