Understand where to maintain an entity’s object attributes

For MES entities that are created from System Platform objects, changes to the object’s attributes are one-directional—that is, from the System Platform IDE to the MES database. There is no mechanism to update the object’s attributes if the corresponding entity’s properties are changed in the MES database using MES Web Portal or MES Client

Also, when Entity Model Builder is run, it overwrites the entity’s property settings in the MES database with the current object attribute settings. So if you make changes to such an entity’s object attributes outside the System Platform IDE equipment model (for example, using MES Web Portal or MES Client), those changes will be overwritten by the Entity Model Builder the next time it is run.

For this reason, once you create an MES entity using an object and Entity Model Builder, you should only maintain the object’s attributes in the System Platform IDE.
