SLA Report in MM

Hi,

I wonder if there is any service level report based on Material ABC type. I want to see what our service level is for Material belongs to ABC.

For example Material has ABC type "A" and we received hundred requests/orders to issue that material within a month and we provided goods 70 times.  This should be a 70% service level and we want to know how long it took to fill the orders.

Please let me know If MM or any other module provide report for above requirement.

Thanks,

Shah.
