| Poor System Integration Testing |
11. No integration testing with external components
SAP integrates with many legacy systems via interfaces, IDOCs, conversions, BAPIs, connectors, or even middle ware such as Mercator. SAP can even be integrated with other commercial ERP systems, forecasting/planning systems, and CRM applications.
Although, the integration of SAP with other systems is critical to the successful implementation and deployment of SAP, many companies merely test during the integration test the interaction of SAP among its various modules and add-ons. Although the aforementioned type of integration testing is necessary it is also critically important to test the integration of SAP with non-SAP systems.
Some examples of integration testing that I have conducted between SAP and non-SAP systems are: SAP integrating via IDOCs to bar coding software, SAP properly sending outbound data to legacy system and the legacy system processing the data correctly, end to end financial reconciliations between SAP and data warehouses, integration between SAP and planning systems for MRP runs, etc. |
