My user is getting following issue at the time of running depreciation for period 1 of 2010:
Create document number range 24 using external number assignment
Message no. AA759
Processing had to be terminated, since you set up the document number range 24 for the year 2010 with internal number assignment.
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.
Change the number range 24 from internal to external number assignment in Asset Accounting Customizing.
