Supply chain models in AVEVA Unified Supply Chain use shared objects, such as process unit models, which may be maintained by other users. The supply chain model may also use feedstock assays, which may be maintained by a different user.
When a supply chain model is created, a copy of each shared object is included within the supply chain model. When the original shared object is updated, the copy in the supply chain model is not affected, and therefore is no longer up to date.
To synchronize the supply chain model with the latest shared objects, run the Model Update Wizard. This detects which shared objects are out of date and allows you to choose whether to replace the old copy with the updated object.
Follow these steps to run the update wizard.
