What must be configured to allow cross-company-code transactions?

To facilitate cross-company-code transactions in SAP, configuring clearing accounts is essential. When transactions involve different company codes, clearing accounts serve as intermediary accounts that help manage intercompany balances and ensure accurate financial reporting.

When transactions occur between company codes, they need to be recorded in a way that maintains the accounting integrity of each entity involved. Clearing accounts allow for the temporary holding of values until the final transaction can be appropriately settled. This setup is particularly important because SAP requires that intercompany transactions ensure that each company code maintains its own distinct ledger while still allowing for the necessary inter-company accounting entries.

While account types, posting keys, and special G/L indicators are important components of SAP's financial accounting functionality, they do not directly enable or manage cross-company code transactions in the way that clearing accounts do. Thus, the configuration of clearing accounts is vital for effective handling of transactions that span multiple company codes.
