Identifying and developing an ERP interface

When working with ERP and other manufacturing software systems, it's important to understand the difference between an ERP interface and ERP integration. In this expert response, learn about developing ERP interfaces.

Which types of manufacturing software are the easiest to integrate with ERP? For example, is manufacturing execution system (MES) software easier to integrate with ERP than, say, product lifecycle management (PLM)?
It is important to understand the difference between ERP integration and an ERP interface. Integration implies different programs reading a single source of data structures. Interface means data is physically transferred between systems.

Third-party packages are usually interfaced, and developing interfaces is never as easy as the vendors claim. Second, even though the vendors provide interface utilities, no matter how well designed and tested they are, you will still encounter interface limitations and other issues.

As for interfacing ERP with shop floor systems versus PLM, you can generally expect a looser handshake between shop floor execution and the planning systems of ERP. This means the number, frequency and complexity of interfaces with MES software are likely less stringent than PLM. But this is not universally the case. It depends on the ERP software in question and the specific functions used in the third-party software.
