How to customize tax codes and depreciation rules in SAP Cloud

[AlbertFeng]

The standard functions do not support Rwanda, where the fixed asset depreciation method and taxation are quite special. How can I customize the depreciation method and taxation strategy in this case?

Hello @AlbertFeng 

Below is a summarized Tax code and depreciation rules

Requirement	Recommended Approach
Special Depreciation Methods	Create custom depreciation keys using SSCUI (Manage Your Solution)
Set up additional depreciation areas (e.g., for tax vs IFRS reporting)
Rwandan Tax-Specific Adjustments	Use manual journal entries or custom fields to capture tax treatment.
Use BAdIs or key user extensibility if automated tax calculation is needed.
Reporting & Compliance	Use standard reports (e.g., Asset History Sheet) or custom CDS views
Export to Excel or SAP Analytics Cloud for tax authority formats
System Limitations & Compliance	stay within Public Cloud restrictions (no backend ABAP mods, only approved logic)

This reflects SAP’s official extensibility strategy for Public Cloud. If Rwanda’s depreciation rules require functionality not available via SSCUIs or extensibility, you may need to:

• Raise a feature request via SAP Influence Portal, or
• Consider SAP S/4HANA Private Cloud, which allows full customization

Let me know it helps
