How can i know someone delete or remove my MRP requirement.

Hi,

I have many cases recently where my MRP ask me to purchase parts via Purchase Order. I have complete my purchase order but the next day, i found that the MRP ask me to delete this order as there is no more demand required.

Understand that there must be someone removed the requirement for the top parts and caused all components and raw material are now request to cancelled.

Questions: Is SAP, is there any way that we can know from MRP (MD04/MD05), which requirement is being removed and caused all this cancellation?

What i can see now is that the MRP ask me to cancel the PO. But i do not know why this is being cancelled..

Appreciated your prompt reply.. Thanks..
