Negative consumptions process order

Hello PP colleagues !!

I'm using PP-PI, and sometimes I have to reverse consumption to process order for a partial quantity. I use tcode MB1C with movement type 262. The situation is that SAP let me post a higher quantity than quantity post in the 261 movement type. It is an issue for me because the user makes mistakes and the order finish with a negative consumption and false positive deviations also the stock increases with a fictitious good receipts.

How to restrict the process order to avoid negative consumption. Can you help me please ?
