Material Master Number Range

Hi,

I have to create 3 Groups - Group-INT, Group-EXT and Group-INT & EXT with material types assigned to them.

For Group-INT & EXT: I have to assign only 1 material type.

Requirement is to create 2 NRs as follows,

1. EXT as 000000000000100000 to ZZZZZZZZZZZZZZZZZZ with NR number as "01".

2. INT as 000000000000010000 to 000000000000099999 with NR number as "02"

Once I have created both Group-EXT and Group-INT, NR number 01 and 02 got generated respectively.

But when I am creating Group-INT & EXT and try assigning Existing NRs ie. 01 and 02, I am getting a message "Intervals already exists"

Not able to create group having both NRs.

Please help.

If I am putting NR values directly then, NRs 03 and 04 gets created with overlap message.

Kindly help me asap with your valuable answers.
