Unable to define number range

Hi All,

I am unable to define number ranges for provisioning CUP Requests.

I had created a number range number 12 in Maintain number range via object GRCREQNUM1 (created by me); however, it is not getting reflected in the define number range node to mark it active for usage.

Please suggest.

First screenshot for number range maintained.

Second one, when I go to Define number range node, then when I create new entry, please find the error screenshot below:

Thanks,

Regards,

Shruti
