Vendor dates move. A supplier gives you a dock date, then the next call pushes it out by two weeks. If your purchase order only tracks one date, you lose the history of what changed and it becomes hard to measure vendor reliability, plan receiving, and set realistic expectations for production.
Cetec ERP supports multiple date fields on vendor purchase orders, so your team can separate what you requested from what the vendor promised, track revisions over time, and keep planning aligned with the most current expectation.
Why One Date Is Not Enough for Vendor Purchase Orders
If you only store a single “due date,” you have to overwrite it every time the vendor changes their commitment. That hides the original target, makes it difficult to see how often dates slip, and limits your ability to review vendor performance in a meaningful way.
Vendor PO Date Fields Available in Cetec ERP
On vendor purchase orders in Cetec ERP, your team can track these date fields:
- Dock Date
- Original Dock Date
- Requested Arrival
- Promised Ship
- Need Date

Practical Ways to Use Each Date Field
Each manufacturing business should agree on what these dates mean internally so purchasing, receiving, and planning are looking at the same signals. A simple approach is to treat Dock Date as the current best expectation, and use the other fields to preserve history and intent.
- Dock Date: The most current dock date, or the date you expect the material to arrive at your facility.
- Original Dock Date: The first dock date that was set on the purchase order, useful for measuring how far the schedule moved.
- Requested Arrival: The date you asked the vendor to have the item on your dock.
- Promised Ship: The date the vendor says they will put the material on a truck headed to your warehouse.
- Need Date: The internal date your manufacturing business needs the material for orders.
- Estimated Pay Date: The date you expect to pay the vendor for what you are buying.
When you are deciding which date to run planning off of, pick one “primary” field that represents what your team currently believes will happen, then keep the others as supporting context. That keeps receiving expectations realistic while still giving you the history needed to review vendor performance.
Key Takeaways
- Multiple PO date fields let you separate what you requested from what the vendor committed to.
- Keeping Original Dock Date intact makes vendor reliability easier to measure over time.
- Dock Date can represent the current best expectation for receiving and planning.
- Promised Ship and Requested Arrival help explain why a date changed and who drove the change.
- Agree on internal definitions so purchasing, receiving, and planning use the same signals.
Conclusion
Vendor dates change, but you do not need to lose the record of what changed and when. By using the vendor purchase order date fields in Cetec ERP consistently, your team can plan to the current expectation while still tracking how well suppliers meet their commitments.
