Block the Material at Item level in Sales Order automatically for delivery

Hi!

My business scenario needs a material to be Ckecked for Inspection after raising the Sales Order by thirdparty person. So, I need to block that particular material at Item level automatically for delivery and rest of the line items can get delivered. I can do this by selecting the reason for Block at Item level manually, but I want the system to get detemine this block. And one more thing is that there is NO Quality Management module for this. So, let me know what I need to configure for this effect. Thank you.....
