@Jae.L , In the situation when a PVO is not available for use in FDI, always check if an Alternate PVO exists, often the required data exists in another PVO that is exposed for BICC/FDI extraction.

• Search the BICC View Object catalog
• Look for:
  • Similar object names
  • Parent objects containing the attribute
  • Child objects linked via keys

Example:
If a detailed transactional PVO is unavailable, sometimes the header or summary PVO is available and can still provide the needed fields.

Hope it helps!
