There are a lot of parameters in configuring your planning. If you have basic stock that you want to keep around you might just have a strategy of keeping a minimum qty around. The min/max coverage code will help drive min. This video gives a quick overview of where to locate the settings and the affect through master planning.

This video was recorded with AX2012 R2 but the same concept applies through all the releases of AX2012.
