Dep number range issue (External Assignement)

Question

Dear All,
i am getting error wile posting Dep (AFAB) for external number range assignment for Document type AF (Dep Posting in Current Year, but in last year it get posted with internal number range only)
See the error.
Create document number range 03 using external number assignment
Message no. AA759
Diagnosis
Processing had to be terminated, since you set up the document number range 03 for the year 2011 with internal number assignment.
System response
You should create a document number range with external document numbers for periodic depreciation posting, since the document numbers are not assigned from Financial Accounting, but by the posting program of Asset Accounting.  The external number assignment, therefore, should not be understood as manually entering the document number.  It is only external from the point of view of the Financial Accounting application.
Procedure
Change the number range 03 from internal to external number assignment in Asset Accounting Customizing.
Why system is behaving like this. It should be internal number range as i post the Dep in  other clients and it is working properly with internal number range.
Kindly Suggest
Regards,
Shayam

Create document number range 04 using internal number assignment
Message no. AA776
Diagnosis
Processing terminated because the document number range 04 for year 2011 was set up with external number assignment.
System Response
For periodic posting of depreciation, you have to create a document number range with internal number assignment, since the document numbers are assigned from Financial Accounting.
Procedure
Change the number assignment for the number range 04 from external to internal in Customizing for Asset Accounting. See SAP Note 890976 for more information.
Now what to do kindly advice.
