Abnormal Termination during Legacy Asset 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 LAND 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?

Thanks
