Planning MDEA Call-Off Orders Under an Annual Supply Agreement

A plant forecasts 240 metric tons of N-methyldiethanolamine (MDEA, CAS 105-59-9) for the year, with deliveries released as inventory is consumed. Turning that forecast into individual orders requires a clear record of which quantities are planned, which are confirmed and when each shipment must arrive.

Separate the forecast from confirmed releases

Provide a rolling forecast to help the supplier assess upcoming requirements. Identify confirmed releases separately, with the quantity, packaging and required delivery window for each.

Scheduling systems can distinguish longer-term planning quantities from firm near-term requirements. Use clearly defined statuses in your own purchasing record so both teams understand what action each schedule line requires. SAP Help Portal

Give each release a complete reference

Link every call-off to the annual agreement and approved specification revision. Include the net product quantity, package type, destination and requested arrival date.

If a release changes, issue the updated quantity or date with a revision reference. Ask the supplier to confirm the revised plan before updating the receiving schedule.

Track the remaining quantity consistently

Maintain separate figures for received quantities, confirmed open releases and unreleased requirements.

For a hypothetical 240 MT annual plan, if 80 MT has been received and 40 MT is confirmed for future delivery, the remaining unreleased requirement is 120 MT, assuming the annual plan stays unchanged. Review that balance when consumption forecasts or delivery quantities change.

Carry batch requirements into every shipment

Confirm that each release uses the applicable grade and specification. Request the batch COAs, packing list and shipment references required by your receiving team.
