when you enter a PP-PI order over COR3 you can go to GoTo - Costs - Analysis.
Now I search for a TCode which will show me such a report for multiple PP-PI orders with the possibility to delect also for material within a time frame (e.g. 01.01.2015 - 30.01.2015).
Currently I think that there is no report like this.
Hopefully you have an idea without development.
MAny thanks in advance.
