Symptom
When switching between items in tab 'Custom Fields' of Display Billing Documents app or Change Billing Documents app, the following error occurs:
- Requested function PFCX is not available here
Environment
SAP S/4HANA Cloud
Reproducing the Issue
- Open an invoice in app Change/Display Billing Documents
- Click into an item and navigate to the tab 'Custom Fields'
- Click on the button 'Next Item' in the navigation bar
- The error 'Requested function PFCX is not available here' occurs
Cause
When you choose 'Display Billing Document' in the 'Process Flow' section, around second 30 in the video, you navigate to the older 'Display Billing Document' App. Unlike the App 'Manage Billing Documents' this is not the main UI for handling Billing Documents, and there are fewer enhancements to this older App. The switch between items in special Tab 'Custom Fields' has never been built in this app.
Resolution
This is not supported in Display Billing Documents app or Change Billing Documents app.
To see the values of custom fields across several items of a Billing Document, please enhance the table in section 'Items' in App 'Manage Billing Documents' by adding custom fields (using the cogwheel do change the column selection). The custom fields have to be enabled for UI/Service/SD_CUSTOMER_INVOICES_MANAGE upfront to support this.
