This scope item covers the material and component change-master-controlled mass change process of one or more manufacturing bills of materials (BOMs). To control the replacement date of the follow-up component or material, you first create a date effectivity-controlled change master. When you start the Where-Used List application with the component or material to replace, all BOMs are listed. To replace the component or material of one or more manufacturing BOMs, the BOMs must be selected. The change number is used to manage the phase in date.
The change process is followed by the production process, which uses one of the changed manufacturing bills of materials in the respective change-master validity period.
