 PM, Two-Ticket Localization Topics for China


You can use this business function to meet country-specific requirements in the area of Plant Maintenance (PM) for China.

In China, there are national GB (guobiao) safety standards that apply to maintenance work and work safety in power generation plants. These standards outline the types of work ticket that are required for maintenance work and for compliance with national standards. The standards are commonly referred to as the Two-Ticket (TTS) and Three-Operation Management (TOS) Systems.

The Two-Ticket System business function supports the creation and management of maintenance work and operation tickets in accordance with TTS and TOS standards.
