Hi @FleVidurK,
Yes, this is by design in standard IFS Engineering Revision Transfer, and there is a specific technical and data‑integrity reason why Direct Transfer is restricted when multiple positions are involved, even though:
✅ All positions are in status Assigned
✅ Direct Transfer works for a single position
Direct Transfer is intentionally limited to single-position context because multiple positions can introduce revision and phase‑date conflicts in manufacturing, which IFS prevents at transfer time to protect production integrity.
For multiple positions, IFS requires Detailed Transfer so the system (and the user) can explicitly validate revision handling, dates, and structural consistency.
Revision handling is based on part, not position
IFS revision logic is driven by:
- Engineering Revision
- Phase‑In / Phase‑Out dates
- Inventory revision uniqueness
When the same engineering part appears in multiple drawing positions, transferring them in one direct action can unintentionally:
- Create multiple inventory revisions with the same phase‑in date
- Overwrite revision history
- Cause conflicts in production planning
Hope this will clear out your doubt. Let me know your feedback.
Thanks & Regards,
SN
