Synching instances
When you change a dynamic combo from a database query data source to an SDO data source, instance overrides of data-related properties might cause the dynamic combo to fail at run time.
Consider the following example: a master dynamic combo has a DisplayedField definition set to “customer.custnum,customer.name”. An instance of the dynamic combo overrides this value with “customer.name,customer.contact”. Changing the master to use an SDO data source changes DisplayedField to “custnum,name”. The instance override of DisplayedField will now fail at run time because the field names are qualified with the table name and should not be.
The Synch Instances button is a tool for removing all overrides of date-related properties in all instances of the SDF. When clicked, it displays the following warning message explaining how it works:
Data-related attributes includes these properties:
This Synch Instances function works with dynamic lookups, too, although its real purpose is to help convert dynamic combos to SDO data sources.
