There is no PMIS or Standard Report available for such reports on MTTR/MTBR. But you can achieve through PMIS reports MCJB or MCJC. For example, see the picture. (MCJB)
By clicking on the F4 help here and by selecting the Equipment by equipment list option you can reach a screen IH08, where you can give the Type of Technical Object value and get the list to this MCJB screen. and then Execute. Similarly for report MCJC.
Try this, Best of luck
