Accounting code assigned to the fixed asset.
This code makes it possible to define the accounting allocation terms for entries automatically generated by the software. It is advised to use the Asset accounting codes that define all the modifiers (asset, depreciation, depreciation expense accounts.) and the natures to use during the automatic postings generation concerning the fixed asset (see the Accounting codesdocumentation).
by default, the application suggests the accounting code associated to the category on which depends the fixed asset.
