Symptom
When posting the invoice, the system triggers a different tax procedure (GB) than the company code country (NL), and the error message 'Error in account determination: table T030K key YCOA' appears.
Environment
SAP S/4HANA Cloud Public Edition
Cause
The issue arises due to a discrepancy in the tax account determination which is based on the company code country. At the time of posting, the account determination was still on the old tax accounts. The tax account for the foreign posting needs to be defined after the activation in all systems (dev, test, and prod).
Resolution
Even if RITA is active, the tax account determination is based on the company code country. At the time of posting, RITA was not yet in status '5'. Therefore, the account determination was still based on the old tax accounts (without RITA). They need to define the tax account for the foreign posting (e.g., country/region GB, tax country/region NL, and account 21...) after RITA has been activated in all systems (dev, test, and prod).
