Sally,
Any automatic function is a result of some action. The standard action for your automatic requirement is IE4N. i.e.,Dismantling the Broken spare-part which is an Equipment. This is Equipment because Serialization is a must for Dismantling through IE4N.
But your case is different. You do not have this Serialization (like many others). So there is no relevance of IE4N for you. So you can not expect any automatic movement of Broken material to Storage Location.
If you want to go for exploring some enhancement to achieve this then, a question comes what is the action or what is the logic for the exit code that triggers the enhancement to perform automatic goods receipt by the storage location? If you are clear about it then developing a solution using a exit such as MBCF0005.
Instead, manual creation of this stock of Broken material is practical and done whenever the item needs to be refurbished. I've recently replied to a similar query as under in this thread.
"Had it been serial number case, then, when it is dismantled through IE4N it is moved to store with Damaged (C3) valuation type. We are talking about the no-serial situation. In this case different companies could adopt different methods convenient to them. At our place we do not have any Financial impacts (because we have opted for Zero value for both Damaged and Repaired spares) for whatever practice we adopt for this. So our people use MIGO Goods receipt 202 to create a Defective version of the material at the Source storage location. (For this another option can be mvtTyp 501, but due to some reasons we do not use it) From here they send to the Refurbishment Storage location through MB1B (311). Then the Repairing agency takes it to Order through MB11 (261)."
Good luck
