Thanks a lot - in this case I would use the word material planning.

A note about SAPTerm (which is the right place to look for translations related to SAP projects):

SAP's translations are anything but consistent between their modules/components, and, if possible, you should try to match whatever translation you use with the particular module/component involved. The right-hand column in the results contains the abbreviated name of the component. In the SAPTerm results that I see for this term, the top one is listed as "SCM-FRE" -- pretty meaningless. But, if you hover over that, you can see that the full name is "Forecasting and Replenishment". Also, there is sometimes an arrow/button to the right of those abbreviations that gives a bit of information about related components.

Sometimes if you're lucky, there's a hint of which component you're working with in your text. Other times, you can only guess as to which fits best.
