ERP glossary for manufacturers

In short

This glossary defines 71 terms that come up when a factory chooses and runs an ERP: general ERP vocabulary such as BOM, MRP and WIP; GST terms such as IRN, e-way bill and ITC-04; and trade terms from textile and engineering plants such as KPO, shade lot, heat number and PPAP.

Questions buyers ask

What does BOM mean in ERP?

BOM means bill of materials: the list of materials and quantities needed to make one unit of a product, including process losses. MRP uses it to calculate material requirements.

What does WIP mean in manufacturing?

WIP means work in progress: material that has been issued to production but is not yet finished goods.

What is a KPO in knitting?

A KPO, or knitting programme order, is the instruction to knit a fabric quality from specified yarn lots, against which knitted rolls are received and yield is measured.

What is a heat number?

A heat number identifies the steel melt a piece of material came from. Carrying it through production links each part back to its mill test certificate.
