SAP Message NR751

Hello,

I have a question regarding SAP Flexible Real Estate.

In transaction RE80 I tried to do an exercise with a real estate search and to create an applicant.

When I try to save however, I get the message:

For object REORRR , number range interval 01 does not exist REORRRID

Message no. NR751

Diagnosis

The database table NRIV has the delivery class 'C', i.e. the SAP default settings are only in client 000.

Procedure

Create the missing number range interval in customizing.

Transaction code: REORRRID

When I look at transaction REORRRID however, I see that there is a number interval 1 ranging from 00000000000000000001 to 99999999999999999999. So, I don't understand why this message keeps popping up...

Does anybody know what I'm doing wrong?

Thanks!
