A namespace problem when doing Create InfoArea in bw system

Question

Dear all,
we met a problem when excute a process in our bw system:
our process as follow:
rsa1(Data Warehousing Workbench:Modeling) --> InfoProvider --> Create InfoArea
then a error message window came out as below.
error in object editing
No valid change license available for n
/BPR3R/
Choose 'Display object' or 'Cancel'.
its detail message is as follow:
Message no. TO127
Diagnosis
You cannot edit the object AREA 0INDUSTRIES. This may be due to the following reasons:
The corresponding namespace /BPR3R/ is not entered in the namespace table with a valid change license.
In the namespace table there is no entry with a valid change license that matches the template /BPR3R/.
System Response
The function terminates.
Procedure
Check the name of the object AREA 0INDUSTRIES. If necessary, choose another object name.
Otherwise, let the system administrator check the change licenses of the namespaces in your SAP system.
Maintain the namespaces in the Tools of the Transport Organizer under Administration -> Display/Change Namespaces.
You need to check and correct the entries that match the template /BPR3R/.
You need to distinguish between the following cases:
The namespace is /0SAP/:
Make sure that the namespace role is C (recipient) and the flags SSCR popup and SAP standard are activated. The license fields remain empty.
You did not create the namespace yourself. Instead, the namespace owner is SAP or another software vendor.
Make sure that the namespace role is C (recipient). The field Repair license must either contain the valid license, or the flag SSCR popup must be activated. Contact the namespace owner and ask what you should now do, and what the valid repair license is.
You are the namespace owner:
Proceed according to the documentation on applying for and setting up namespaces. If the namespace role is P (producer) then you need a valid development license. For information on this, see the SAP Library under BC - Basis Components -> Change and Transport System -> BC - Namespaces and Naming Conventions -> Reservation of Namespaces).
Then we did the below action:
se06 --> system change option
in this view, we found  /BPR3R/ this Prefix.
And it is empty in  /BPR3R/ 's namespace/name range volume.
What is next action we should take to solve this problem?
Anyone experienced or expert,
Please kindly give advice.
Regards,
Allen
