Supply against a part will be generated by its available stock position relative to its
buffer and zone levels. For example, consider four parts (r457, f576, h654, and r672).
These four parts are assigned to a specific planner (GSC).
Figure 26-12 shows the difference in relative buffer position between a calculated
available stock level and actual on-hand. The black arrows indicate the on-hand position,
and the no-fill arrows represent the available stock position. This type of visibility gives
