Answer 1

For doing ABAP within APO, some useful things would be.
1. Pulling data from Livecache/Memory - best ways to do this. ie which BAPI's and Function modules, and wether it is order series of time series from DP. (below is an example of some test code with some hard coded numbers to pull some PPDS orders out for testing)
2. Find out what areas the business are using the most / struggling the most and dig into what is possible. There is often a mix of configuration changes or code which could do the same thing.
Code example with specific hard coded material and exact order ID to review results.
