OBR2 - Reset the number ranges if required

Hi experts,

I had created 3 accounts by mistake and I am trying to use transaction OBR2 to delete them.

When I execute the transaction I got the below error:

Message no. BL001 - Reset the number ranges if required

Even though there is not any posting on the accounts, I am not able to delete them.

Another point is that the company code is not productive. The test has been doing on Dev environment.

Does anybady has any concern about that?

Thanks in advance,

Daniel
