MTTR/MTBR report......

Dear All,

As per my knowledge we have mttr/mtbr reports straightway available in system, but they calculate from the start date till current time..............accumulative.

But if i want some month wise comparison, or monthly MTTR/MTBR reports,,,,,,,,and others like COST Comparison,,,do we have available in SAP??
