Zusammenfassung:In a method of and a system for managing product definition updates in the control of a manufacturing process via a MES system, design information entities each defining manufacturing specifications for a specific product and including sets of data concerning different manufacturing steps are downloaded to the MES system (100). At the first download, first and second MES information entities (in short, first and second entities) are created within the MES system and stored into a database (101). The first entities have associated second entities each including data for a manufacturing step for that product and include links to the associated second entities in the database. At each update of a design information entity (102), a differential package including the whole of the data for a set having undergone changes and for newly added sets, and an identification for unchanged sets, is downloaded to the MES system (103). A new version of the second entities corresponding to sets having undergone changes and/or additional second entities corresponding to sets of data that have been added are created and stored into the database (104), and a new version of the first entity is created (104) by: replacing, for an updated second entity, the link to an existing version of the entity by a link to the new version; adding links to newly created second entities; and deleting links to second entities corresponding to sets of data deleted from a design information entity.
