Plant maintenance BOMs contain items that are only used for structuring the equipment (PM assembly). No plant data is required for these materials. For this reason, the system does not check plant data for items with the item category PM structure element.

Only use items of this item category in plant maintenance BOMs (for example, equipment BOMs, material BOMs that are relevant to plant maintenance, and functional location BOMs).

A valid material master record must exist in the plant you select.
