Dear friend,
If you don't give information about situtation of your materials to SAP, system can not know anything about their status whether they are damaged or not. Therefore, you should give information about them.
If you want to follow your materials, you can use quality stocks or smth.
or, if you want to follow your material in manual way, you can create a new storage locations such as wrong material SL or damaged SL or unpackaged material SL. For example, when you recieved damaged material, you can make the Goods Receipt by using "damaged material Storage Location"
Sincerely
Beste
