You are going to have very limited options. PwC does not have a native connector to Anaplan. That leaves ODBC/JDBC/API access.
I cant seem to find any odbc drivers so that may be out.
PwC doesnt support JDBC so that is out.
Anaplan has a REST API layer but PwC doesnt support REST. (you can do thru HTTP but very limited)
The Informatica cloud does have a native connector which I would recommend taking a look at.
