Rework confirmation

Hi All,

When Iam doing confirmation for 100 pcs (yield 90,rework 10), how and where the rework qty of 10 pcs get captured ?

As I want to create the separate order for rework which I am planning to do by co01.

In my friend company, while confirming 100pcs (yield 90,rework 10), full 100 pcs is captured in stock against one batch no.111 and then manually create rework order and in BOM of that order they remove the raw materials and add the goods to be rework and any extra material needed and qty with batch no.111.

while confirming this order, it generates one more batch no.112, but this is not working in my company, can any one explain this.
