update OUSR activate deleted user wrong

Hello,

Signed up a user in SAP B1 and saw that the code was wrong, was minuscule, and tried to delete it again only register that gave error saying it already existed.

I realized that deleting the user, it changes the group table OUSR from 0 to 99

I wonder if I can run the following command window using the "Query Manager"

"update ousr set groups=0 where userid = 35"

The user is new, never been used,

Thank's

Fabio.

PS: sorry for the syntax, I'm using google translator
