Approval worflow for any fixed assets modification

Hi,

I am looking for approval process for changes in fixed assets processes like

- Capitalisation of fixed assets

- Transfer of fixed assets

-  Scrap of assets

- Sale of fixed assets

- Disposal of fixed assets

- Stock adjustment (inventory material - accessiories)

Please let me know if you have any standard process or workaround to mange such approval requirement.

Thanks in advance
