NLINK MES TO SAP SOLUTION SAP TRANSACTIONS
The NLINK® MES to SAP Solution comes with a rich set of pre-built SAP Manufacturing-related transactions. Determining which of these transactions are the most appropriate for your particular situation depends on a number of factors, including your project’s functional requirements and which modules of SAP you use. The information presented here will help you make an informed decision.
SAP PRODUCTION MANAGEMENT INTERFACES
These interfaces work with the SAP PP or PP-PI modules, although one or the other is used for a given application. Both the PP module’s routing and BOM (Bill of Material) data as well as the PP-PI module’s control recipe data are mapped to the ISA-95/B2MML production schedule XML schema. This provides a single, standards-based, data format on the manufacturing system side of the interface.
- Download Equipment List
- Send Runtime Data for Equipment to SAP
- Maintenance Request
- Maintenance Work Order
- Maintenance Response
The SAP PM module contains the master list of equipment to be tracked for maintenance purposes. A subset of the master list is downloaded by the MES upon demand. The scope of the equipment list subset is determined by the equipment types to be included.
Equipment (asset) performance data will be accumulated by the MES for defined equipment and periodically uploaded to the SAP PM module. The MES uses the downloaded equipment list to determine the equipment to accumulate data for.
The MES can send a request for maintenance on a piece of equipment to the SAP PM module which creates a maintenance notification. SAP PM module end users can then authorize the maintenance thereby creating a work order or deny the request thereby causing the notification to be closed.
SAP sends maintenance work order data to the MES when there is a change in a work order’s status.
SAP sends information about completed maintenance notifications when work orders are closed out in the SAP PM module.
SAP INVENTORY MANAGEMENT INTERFACES
Material master data is downloaded to the MES to allow the manufacturing system to include information such as costs in real-time displays. The material master download messages are initiated by the SAP system and can be received at any time.
The MES can send periodic spot inventory levels or updates when inventory status (e.g. location, amount, lot ID) has changed to the SAP MM on an hourly or daily basis.
When material is batch managed in an SAP system it is often necessary for the MES system to send the MM module batch characteristic data (e.g., expiration date, operating temperature range) for material lots and to associate this data with a batch ID.
SAP QUALITY DATA MANAGEMENT INTERFACES
The MES receives SAP QM module inspection lot messages. The messages contain lists of lot IDs that require inspections along with the inspection data requirements for each lot.
Using the inspection lot information downloaded from the SAP QM module, the MES can send quality test result data for specific lots to the QM module.
There`s really only so much information you can absorb by reading about an enterprise software product like the NLINK MES to SAP Solution. At some point you need to see the software in action and that`s what the NLINK MES to SAP Solution Video Presentations are all about.
