Doubts about Integrated Planning

Hello,

We have started a new project for SAP BPC 10.1 in embedded IP model. I have never worked with BW-IP, I have some questions that I would like to ask:

1 same extractors can be used both for master data and transactional data as the current model of SAP BW or use specific extractors for IP?

2 to define a new InfoCube IP is necessary to be always in real-time mode set?

3 on stage that we consider need to hand load current data and also data plan, which is the best solution to do this:

a create a single infocubo for current data and data plan

b. create 2 InfoCubes, one for current data and one for the data plan, define both InfoCubes in real-time mode and use a multiprovider with 2 InfoCubes.

4 would help me a lot if I could provide facilitate documentation on best practices for defining modeling with IP, as well as other types of IP-related documentation.

Thank you very much for the help,
