SAP Implementation – customising und programming in SAP ERP and SAP EWM
Once the requirements have been defined in the SAP business blueprint, they are implemented. The implementation phase is divided into three steps:
- Implementation (customising, programming, developer tests)
- Offline tests and offline performance assessment
- Preparation of key user documentation; key user trainings
- Customisation of SAP EWM, SAP MFS, SAP WM, SAP S/4HANA and SAP ERP
- Use of our own applications (standard-in-standard)
- Migration to SAP EWM (from non-SAP or SAP WM)
- Emulation and simulation of automated warehouse systems
- Test cycles: offline, online, integration, performance tests
- Customizing von SAP EWM, SAP MFS, SAP WM, SAP S/4HANA und SAP ERP
- Einsatz unserer Applications (Standard-im-Standard)
- Migration nach SAP EWM (von Non-SAP oder SAP WM)
- Emulation und Simulation automatischer Lagersysteme
- Testzyklen: offline, inline, Integration, Performance-Tests
We apply an agile approach to the implementation phase. Once functions and dialogues have been developed, we give the client hands-on demonstrations in so-called “development checkpoints” and discuss the results. This constant interaction in the course of the project
- ensures effective cooperation and information exchanges in joint project teams
- reduces reaction times and decision-making
- prevents the project from taking wrong turns of direction
Before the functions and processes are handed over to the client for offline tests, we test them on the development system and internally document the results. They are then transferred as complete modules from the development system (D) to the client’s test or quality system (Q).
To begin with, a test plan is created based on a process list (traceability matrix) from the SAP business blueprint. The offline tests are carried out by the client’s key users. Upon request, ioDigitalSolutions can take on the test management role. The offline performance assessment concludes the implementation phase and takes place using the actual interfaces between SAP EWM, SAP ERP and MFS. All other interfaces (e.g. to the secondary controls) are tested using emulations.
In addition to the offline tests, we carry out, together with the suppliers of the logistics equipment and machines, simple online tests to check that all communications and couplings for the exchange of telegrams and telegram sequences work properly.
Train-the-trainer is a well-established training concept that ensures optimal SAP EWM and SAP MFS knowledge transfer to key users over the course of a project. Ideally, the users are already involved in the actual implementation and offline tests, for them to gain a deep understanding of the system. We provide key user documentation for the respective processes or modules to assist you.
This step serves to test for correct and efficient interactive performance of all the system components – i.e. the mechanical equipment, SAP MFS and SAP EWM – under realistic operating conditions, and to make any necessary adjustments.
The focus is on:
- End-to-end tests under real conditions (e.g. container barcode scanning, label printing)
- Getting the facility up and running (processes, system performance, troubleshooting) together with the logistics supplier
- Performance or mass tests (subordinate and online with data via the interface)
The online performance assessment (system performance test) concludes the commissioning phase, serves as the transition to go-live preparation, and is carried out under real conditions with the actual physical and logical interfaces.
