3343015 - Accounting Data tab not available app Change/Display Billing Document (VF02/VF03) - S/4HANA Cloud

In one CRM related scenario, you might need to check some Accounting Data in follow-up billing document, such as Per. of Perf. Start and Per. of Perf. End. Howver the Accounting Data tab is only avilable in app Manage Billing Document rather than app Change/Display Billing Document (VF02/VF03).

As a workaround, to access the two fields: Per. of Perf. Start and Per. of Perf. End, you can create a custom CDS view with data source I_BillingDocumentItemBasic and add these two Elements:
I_BillingDocumentItemBasic.BillingPerformancePeriodStrDte
I_BillingDocumentItemBasic.BillingPerformancePeriodEndDte.
