3800756 - Error Message "G/L account is not defined in chart of accounts" occurs when releasing a billing document - SAP S/4HANA Cloud Public Edition

When releasing a billing document, the error message "G/L account is not defined in chart of accounts" occurs and the billing document fails to post to FI side.

SAP S/4HANA Cloud Public Edition

1. Open the app "Change Billing Document" and enter the affected billing document number.
2. Click on button 'Release to Accounting'.
3. Observe that posting fails with the error "G/L account is not defined in chart of accounts YCOA."

A possible cause is that there is no account key assigned to the relevant condition type in the affected pricing procedure.

As a result, the GL account is not determined and when this condition line is posted to FI side, an error is raised. 

Maintain the correct account key for the relevant condition type in the configuration activity "Set Pricing Procedure". Ensure the appropriate account key is assigned so that the G/L account can be determined correctly during billing document release.
