Importing Data from Fixed Assets Add-On 
With the fixed asset data migration wizard, you can migrate the following data from the Fixed Assets add-on to SAP Business One:
Account determination
Depreciation areas
Depreciation types
Asset classes
Asset master data
When importing the asset master data, the system can only copy the asset values at the beginning of a fiscal year from the add-on to SAP Business One. Usually, this is the year to which the last fiscal year change is carried out in the add-on. If asset transactions take place during the fiscal year, you must manually create these transactions in SAP Business One as the transactions cannot be imported.
For example, in the Fixed Assets add-on, asset X has a net book value of 5000 USD on January 1st, 2012. On October 1st, 2012, the asset retires completely and becomes inactive.
In November, you import the asset-related data from the add-on into SAP Business One. After the import is completed, you can find asset X in SAP Business One with a net book value of 5,000 USD at the beginning of fiscal year 2012. There is no record of its retirement and the asset is still in active status. In this case, you must create the asset retirement transactions in SAP Business One all over again.
