How FAST MES connects to SAP ECC
Partner MES connector to SAP
delaware describes FAST MES as connecting to SAP and buffering locally. In ECC, MES integrations typically release process or production orders to the floor and confirm progress back through standard confirmations. That is general practice, so confirm the objects used with delaware.
Local buffering
Data is kept locally so that operators can continue when SAP is unavailable and transactions sync when it returns. Ask how conflicts and ordering are handled after a long outage.
What data moves
| From | To | Data | When |
|---|---|---|---|
| SAP ECC | FAST MES | Released production orders, routings, BOM components | Order release |
| FAST MES | SAP ECC | Operation confirmations: yield, scrap, time | Operation completed at the station |
| FAST MES | SAP ECC | Goods issues and receipts for production | Material consumed or finished goods produced |
| FAST MES | SAP ECC | Buffered transactions replayed | SAP connection restored |
Setting it up
- 1Scope the plant and processesPick the lines, order types and transactions the MES owns, and what stays in SAP.
- 2Confirm interface and versionsGet the supported ECC and S/4HANA releases and the exact SAP objects used from delaware.
- 3Align master dataCheck routings, work centres, operation numbers and confirmation parameters, because the MES executes what SAP defines.
- 4Connect shop floor equipmentIntegrate stations, scanners, scales and machines according to the project design.
- 5Test outage scenariosDisconnect SAP during a shift, run production, reconnect, and verify nothing is lost or duplicated.
- 6Go live line by lineStart with one line, reconcile confirmations and inventory daily, then expand.
What usually breaks
- !Confirmations replayed after an outage hitting orders already closed or changed in SAP.
- !Backflush settings in SAP and MES goods issues both consuming the same components.
- !Operation numbers or work centres that differ between routing and MES configuration.
- !Clock differences between shop floor and SAP creating odd timestamps.
- !Long outages exceeding buffer capacity or operator patience.
A private AI layer across both systems
Order status in plain language
Ask where an order stands and why it is behind, answered from SAP and MES events with timestamps and sources.
Sync failure triage
After an outage, list buffered transactions that failed to post, group them by cause and draft the correction for a supervisor to approve.
Scrap and yield review
Compare MES scrap and yield with SAP standards and surface where routings or BOM quantities look wrong.

When something else fits better
- SAP Digital Manufacturing offers an SAP-native MES route if you want to stay with one vendor.
- SAP production order confirmations entered from simple terminals may be enough when traceability needs are light.

Frequently asked questions
What is the main benefit of FAST MES with SAP?
delaware says it connects SAP ECC or S/4HANA to the shop floor and buffers locally so production continues during SAP outages. Whether that matters to you depends on how often SAP is unavailable and how costly a line stoppage is.
Which SAP objects does it use?
The public page does not list them. MES integrations commonly use production orders, confirmations and goods movements, but ask delaware for the exact interface and any custom development your plant needs.
What happens during an outage?
Per the vendor, transactions are buffered locally. Test the full cycle yourself: disconnect, run, reconnect, then check confirmations, inventory and duplicates. Agree what operators do if the outage is longer than planned.
Can AI run on top of MES data?
Yes, as a read-only assistant over MES and SAP data that explains delays and triages failed syncs. Keep it on your own network for sensitive production data, and require approval for any corrective posting.
