Material master identification

Hi all,

We have thousands of material code and batch in our SAP system . Lots of material code and batch is not at all used but it’s available in SAP. How to trace material and batch which is not at all used in any transaction so we can block the same.

Right now we are doing this through PR, PR and Mseg table . IF no transaction is available in this tables then we block material code but is there any other way to do the same.

Thanks
