Error during asset master conversion

I am trying to load legacy asset master data and at the end of LSMW step it gives me the following error;

ERROR MESSAGES FROM DEPRECIATION CALCULATION

Asset INTERN-00001 0 Book Case CoCd. G213

E698 SYST: Abnormal termination (ANLB-LGJAN 1 not equal to ANLC-GJAHR

The mentioned fields are not part of the load file, any ideas on what may be causing this error?

I am converting as mid-year of 11/30/2008 where i load all prior year as of 12/31/2007 and manually capture all 2008 capitalization and run unplanned depreciation from Jan 08 thru Nov 08.

Thanks
