I have a feature class of our Sign Posts and a table of Signs.     The signs are related to the SignPosts.    I was struggling with trying to update a unique ID in Web AppBuilder so I contacted ESRI.    I was looking at a trigger in ArcSDE, but ESRI support told me that that is not supported.    The ESRI support Analyst said,  why not use the ObjectID?     I always thought this was not encouraged because ObjectIDs can change when exporting.    


Is this a change in thinking from ESRI or was my understanding wrong all along?    What are the downsides of using the ObjectID other than the export issues? 


Using the ObjectID certainly makes life easier for me,  but was surprised to hear ESRI suggest this.
