the error message sound pretty clear. have you checked that number range?
It is somewhere in the IMG, though I don't know it from the top of my head. You can use transaction code SNRO and then select number range object HR_GB_HEID. Check the intervals. You mau have to create interval 01 - and make it" internal".
If it hasn't been used yet, you can also transport it from the development system, if it works there. Obviously, if any interval has been used already in production, refrain from transporting.
The error should be gone as soon as the number range exists.
