Generally, when the error "Asset incomplete and has to be completed" is displayed check the asset listed in the report of T-code AUVA and in T-code AW01N.
There is another error behind. It could be for example AA 669. You will find such error message in AW01N.
With the report RAUNVA00 (T-code AUVA) you can identify the cause of the incomplete asset. The report will show all the incomplete assets for a company and it will identify for example the field which is causing the asset to be incomplete. By double-clicking on the line for an incomplete asset,you can access master data maintenance.
Could you please check if you have any depreciation pending in the closed year? (execute AFAB in restart mode) also ASKBN.

You are running a Test Run in AJAB. In this system will list out any error occur during year end closing.
Please Uncheck the Test run Check box then run this program in background.
Then execute SM37 and press execute. there you will see a job name 'RAJABS00'. open then Spool. there you will see that Year close carried out.
Then Check OAAQ.
As Guneetinder singh told, you have to got o sm37 and check the error logs , from that you can identify the problem.
One possible problem may be the negative value with the asset. If it is negative value, go to the particular asset master, on depreciation tab double click on depreciation key. One screen will popup, and there you need to tick negative value allowed field. If negative value allowed field is not visible, you have to edit screen layout rule.
