How to mass delete materials in a storage location

We have just emptied a storage location with stocks, and our company wants to block that

certain storage location from goods movement in case it'll be accidentally use.

As I have learned, one way to "block" a SLOC is to flag for deletion the materials.

Since that particular SLOC contain thousands of materials, MM06 is out of question.

I have encountered MM17, but the problem is, I'm not familiar with it.

Any idea how to use it? If possible step by step.

Any info would be much appreciated.

Thanks,
