1. SAP S/4HANA Help Portal
"Perform Foreign Currency Valuation": In the configuration for automatic postings for foreign currency valuation
the documentation specifies the need for a "Balance Sheet Adjustment Account". It states
"For the valuation of open items in G/L accounts
customer accounts
and vendor accounts
you also have to specify a balance sheet adjustment account." This account is used for the offsetting entry for the exchange rate difference. (Accessed under SAP S/4HANA Cloud/On-Premise -> Finance -> General Ledger Accounting -> Periodic Closing -> Foreign Currency Valuation).
2. SAP Learning Hub
Course TS4F02 - Financial Accounting in SAP S/4HANA - Academy Part II: In the unit on "Closing Operations in General Ledger Accounting
" the foreign currency valuation process is detailed. The configuration section explicitly shows the account determination screen (transaction KDF) where a "Bal. sheet adj. acct" is required for open item valuation
confirming that an adjustment account
not the reconciliation account itself
is used for the balance sheet posting. (Refer to Unit 6: Closing Operations in General Ledger Accounting
Lesson: Performing Foreign Currency Valuation).

"Financial Accounting with SAP S/4HANA: Business User Guide" (2021)
Chapter 15
Section 15.3.1 "Account Determination": This guide explains the configuration for foreign currency valuation. It clarifies that for open items
"the system posts the valuation difference to a balance sheet adjustment account and an expense or revenue account for exchange rate differences." This directly supports the use of an adjustment account.
