Chapter 14 closes out the FI global settings block. It is short but specific: inflation accounting for companies operating in high-inflation countries. If you are running SAP in Chile, Colombia, Mexico, Venezuela, or Turkey, this chapter matters. If you are in a stable-currency economy, skim it and move on.

What inflation accounting does

Inflation accounting revalues fixed assets during closing to reflect current costs instead of historical acquisition costs. You use an inflation index (a statistical measure of price changes over time) to adjust selected G/L accounts when preparing financial statements.

In SAP, the Asset Revaluation (Inflation) Program runs monthly at close. It calculates revaluation amounts stored in the asset sub-ledger. During the depreciation run, those amounts post to G/L alongside regular depreciation.

New assets need a revaluation key in the master record. Inflation index values get updated in customizing whenever the government publishes new figures.

Revaluation amounts live in revaluation areas, which are essentially special depreciation areas alongside your regular APC and depreciation tracking.

Two types of inflation index

SAP requires two indexes:

1. General inflation index - broad price level changes. Used for most G/L account adjustments.
2. Specific inflation index - price changes for particular goods or services (gold, silver, real estate). Used only when government rules demand it.

SAP ships sample indexes for Chile, Colombia, Mexico, Venezuela, and Turkey. Copy and update them, or build your own. You may also maintain composite inflation indexes that combine multiple indexes into one.

Example from the book: Chilean government requires real estate assets adjusted with a specific index. Instead of applying general and specific indexes separately, you can define one composite index that blends both.

Customizing activities

The full setup list:

• Maintain inflation indexes
• Maintain time base and exposure to inflation variants (TBE variants)
• Maintain inflation keys
• Display inflation key field in G/L account (per activity or per account group)
• Assign inflation keys to G/L accounts
• Maintain inflation methods
• Assign inflation methods to company codes
• Assignment of inflation indexes to line items
• Maintain inflation adjustment accounts
• Maintain G/L accounts for inflation postings

That is a fair amount of IMG work before the first revaluation run.

TBE variant: timing the adjustment

The Time Base and Exposure to Inflation Variant (TBE variant) controls when and how often items get adjusted.

Say you adjust fixed assets quarterly. Define a TBE variant for quarterly adjustment. You can also set rules for mid-period acquisitions. Equipment bought on 15 March gets treated as if acquired on 31 March (last day of the adjustment month). But for the April adjustment, the full month counts.

This prevents partial-month distortion while keeping the quarterly rhythm clean.

Inflation key: what gets adjusted and how

An inflation key controls how a specific G/L account gets revalued:

• Which inflation index applies
• Whether the account balance alone gets adjusted or individual line items do
• Other adjustment parameters

Assign inflation keys on the G/L master record under Control Data.

Inflation method: company code level control

An inflation method bundles all settings for a company code’s inflation program:

• Which accounts need adjustment (assets, materials, etc.)
• Which general inflation index to use
• Which TBE variant applies
• Document types for inflation adjustment postings

Three sections per method: FI, FI-AA, and MM. If both asset accounting and materials management are active, configure all three.

Assign one inflation method per company code that uses inflation accounting. Standard methods exist per country local version. Modify or create your own.

My takeaway

This chapter is niche but complete. Veeriah does not oversell it. Inflation accounting is mandatory in some jurisdictions and irrelevant in others. The configuration chain is logical: indexes feed keys, keys attach to accounts, methods tie it together at the company code level, and the revaluation program executes monthly.

If you are implementing S/4HANA in a high-inflation country, budget time for index maintenance. Those numbers change regularly and stale indexes mean wrong financial statements.

That wraps the FI global settings arc: ledgers, documents, sales/purchase tax, withholding tax, and inflation accounting. Next up in the book: general ledger deep dive.
