I tried Tcode OONR,But still i need clarification on this.
pls guide me step by step.

Use Tcode OONR

Maintain Number Ranges
     In this step, you specify the number ranges for your PD objects and the
     type of number assignment. You must assign a unique number to every
     object.
     You have the following options:
     o   Internal number assignment
         If you want the SAP System to assign the numbers, enter "IN" in the
         'NR' field. The number ranges are then indicated by the letters
         "IN".
     o   External number assignment
         If you want the user to assign the numbers, enter "EX" in the 'NR'
         field. The number ranges are then indicated by the letters "EX".
     You can define your own number ranges (subgroups) for individual plan
     versions (that are not valid for all plan versions) and object types.
     The names of the subgroups are set up so that the first characters
     specify the plan version and the last two specify the object type in
     detail. The structure of the subgroups depends on whether you are using
     number assignment valid for all plan versions or not.
     Example
     Number assignment for plan version 10 / object type S: Subgroup 10S
     Standard settings
     The entry $$$$ in the field subgroup represents all number ranges not
     listed explicitly. You should not delete this entry.
     Recommendation
     Since the matchcode function is available for the selection of objects,
     it is generally not necessary to assign "mnemonic" numbers.
     SAP recommends that you use internal number assignment.
     Activities
     1.  Enter the subgroup for which you wish to set up number assignment.
         The following entries are allowed (when number assignment is not
         valid for all plan versions).
         -   $$$$ (plan version and object type are generic)
         -   PV$$ (plan version, object type is generic)
         -   PVOT (plan version, object type)
         The following entry is not allowed:
         -   $$OT (plan version generic, object type)
         The following entries are allowed (when number assignment is valid
         for all plan versions):
         -   $$$$ (plan version and object type are generic)
         -   $$OT (plan version generic, object type)
         The following entries are not allowed:
         -   PVOT (plan version, object type)
         -   PV$$ (plan version, object type is generic)
         Save your entries. The systems automatically creates an external
         number range (EX) and an internal number range (IN).
     2.  Specify the subgroup on the following screen and choose "Change
         intervals".
     3.  A new data screen appears on which you can maintain number range
         intervals. Choose "Create interval".
     4.  Enter the code for the number assignment (IN or EX), the lower limit
         and the upper limit of the interval in the dialog box which then
         appears.
         In the case of external number assignment, mark the field "ext"
         also.
     5.  Choose "Insert" and save your entries.
