You can assign the number ranges to material type with transaction code MMNR.

You can push the change groups button to do create and assign or change the number ranges for material type.

The material types are called ‘ The Elements ‘ on this screen.

You can enter a name where named group.

You can enter the code what identifies the number ranges on the place that named ‘No’. You can enter any two-character code.

From No. field defines first number to be assigned for internal interval. For external interval it defines the lower limit.

To Number Field last number to be assigned for interal interval. For external interval it defines the upper limit.

The Ext flag is an indicator which determines whether the number range interval is internal or external. For use The Sap System issues the numbers for internal number range intervals automatically. This number is between the from number and the to number. The last number issued is logged in the current number level. You need to enter a number for external number issue. The number you enter needs to be between the from number and the to number.

      The material range interval for one of the material type is almost exhausted in our system.

      We would like to create a new group and assign it to the material type. I wonder if you have faced this issue and if you would this approach is correct.

      Thanks in advance.

      Hello colleague, I tried but I don't have authorization to edit or create. May I know what authorization I should have to edit material number ranges?

      One question - How to set the material number range length to more than 18 characters.

      Already activated the material extended field and material number field length set 30 char. but in the MMNR I cannot maintain the number range length more than 18 char.

      Please advise! Any steps I missed.
