When connecting external systems from ERP via the PI-PCS interface you might want to check the content in ERP first. Here are some hints where to look and what to look out for.

• COFT – Instruction header
• COFV – Instruction content

When looking at the structure (see PI-PCS – Structure) you get from the PI-PCS interface you will notice some differences. I have made a little mapping table to show this: PI-PCS – ERP Table Mapping
