Once you have copied the material type from ROH to 1001.

Check if the NR's are copied over.

Try using the same external number range it should work. check the external number range should not contain alphabets.

Thanks & Regards,

Hi Praveen,

First define the Group & Insert the Number range from 1001 to some range in MMNR.

Assign your Material type ROH or other to that group.

Then when you create the Material in MM01 don't enter the Material number. System will take the 1001 number onwards when you select that material type in MM01.

In External number range system will only consider Alpha numeric no numeric number range.

If you define your own number range then don't enter manually the same number just leave blank & continue in creating the material master system will take the number automatically as per the number range maintained for that Material type in MMNR.
