Fixed Assets - Manual Dep

Hi Experts,

     I'm developing add-on that will import the file to Manual Deprecation in Fixed Assets. I'm wondering what is the Object Type for the fixed asset. I've check the table OACQ the object type is 20. It is the same objecttype for Purchase Delivery Notes. This is my code :

Dim vFA As SAPbobsCOM.AssetDocument            vFA = oCompany.GetBusinessObject() 'I don't know what to put insert in the BusinessObject

Regards,
