The production bill of material is globally specified at the company level. It can be used as a source for the definition of the local material lists, such as:

• The production model in the repetitive module.
• The production model in the job shop module.
• The subcontracting model in the subcontracting module.

The production bill of material can be generated through the engineering bill of material. The new production bill of material differs from the old bill of material:

• It has a header and a status.
• It is always revision controlled.
• The effective dates have been moved from the material lines to the header.
• The BOM quantity has been moved from item production data to the header.
• The use up has been moved from alternatives to the material line.
• The material line excludes logistic data (no warehouse nor routing operation).

The production bill of material is not mandatory.
