If you need to modify the local ID format for an external system, regenerate the application after you make the changes and then redeploy the project. If you extend the length of a local ID past 20 characters, make sure to increase the length of any database columns containing local IDs. Local ID columns are found in the following tables: sbyn_parent_object, sbyn_assumedmatch, sbyn_enterprise, sbyn_systemobject, and sbyn_transaction.
