    Hi Harry,

    For number range, please refer to Olivia's suggestion.

    For MR Reason, I didn't find any IMG to define a new MR reasons. However, If you still want to add a new MR reason, you can use transaction SM30 and maintain table TE609 to add new a MR reason.

    Hi Harry,

    Please see the following regarding the device serial no's:

    SPRO ->

    SAP Utilities

    Device Management


    Basic Settings

    Define Number Ranges for Device Group and Define Number Ranges for

    Logical Numbers of Devices....

    If you see the explaination for Defining Number Ranges for Logical

    Numbers of Devices you will see that it says because the logical device

    number is used internally, you should not create number ranges with

    external number assignment.

    During the creation of devices the table MASE is used as a kind of

    number range object (the next higher possible serial number per material

    is sued) If necessary you can influence the equipment numbers by using the number

    range object EQUIP_NR - equipments. But for device serial numbers there

    is no number range object.


    You can use function module EXIT_SAPLIPW1_008 from enhancement

    IQSM0008 when you create a material serial number and equipment. This

    means that every time you create a device, the corresponding combination

    of material and serial number undergoes further user-defined checks.

    In relation to the MRR I will have a look at get back to you...

    Hope this is helpful for you.
