Copy Data Within a Model

Hi,

I need to copy data from ACTUAL to PLAN. For example, I need to transfer 2014 data to 2015 Plan.

I found the standard package COPY.

A few questions which i hope you can help with

- on the handling of records what is "Copy Records with Match Key" and "Copy by replacting in same data region of Entity, Category, Time and Audit ID"

- Is there a way to restrict the number of options on the dimension selection area. As I want to restrict the options that the user selections? E.g. only allow them to select CATEGORY and TIME?

Thanks,
