Tracing Requirements
Definition
WLT enables you to create WIP lot and serial tracing records at the operation level whenever registered resources are consumed or produced. How you define your tracing requirements determines exactly what tracing records are created. First determine exactly how much tracing your manufacturing environment requires. Once that requirement is determined, you can set up or define your individual tracing requirements.
What to Consider?
• Decide which material to trace based on which routings and BOMs consume components, then create the WIP material you want to trace
• Know the milestone operations
• If there are any lot-sizing restrictions in your manufacturing environment, list these restrictions, organized according to routing, operation, and work center
• If there are any inventory lot quantities issuing restrictions, create records in Routing Registration Maintenance (3.22.13.1) that prevent or allow WIP lot overissuing based on the routing or routing operation
• If inventory reference tracing is required, set up naming and usage standards for references
• Determine if lot splitting or combining is an issue. If so, clearly define the requirements, then use the information to create records in Routing Registration Maintenance (3.22.13.1) and BOM Registration Maintenance (3.22.13.4)
• If you have specific lot/serial number format requirements, create NRM sequence IDs using Number Range Maintenance (36.2.21.1)
