Setting up a one to one relationship in an Entity is straightforward. All you need to do is lookup key values, declare and map it inside entity module configuration on smart forms to store and retrieve information from database. But for complex application user may need to link between entities. ONEWEB supports creating a link between two existing Entities (called Parent and Child Entity) through Parent-Child configuration Linking parent and child entities together offers smooth transitioning from one software module to another.

For instance, it is a good idea for users who are working on the Sale Order screen to be able to switch to Customer Data screen immediately without having to search through the database with CUSTOMER ID. This is very common in enterprise business processes where transitioning between business entities happens frequently.

Note: To see all Configuration property settings of Parent -Child forms in detail please refer Utilities section in Chapter 8 - App Designer Reference.
