Material Master Question: batch mangement (plant) vs batch management (global)

What precisely is the quality betwixt the two? How is the worldly if lone 1 is active?

• how is the worldly effected if only batch absorption (plant) is progressive and batch absorption (global) is inactive?
• inversely - however is the worldly effected if only batch absorption (global) is progressive and batch absorption (plant) is inactive?

Any penetration connected this would beryllium greatly appreciated, thanks!
