Entity extension considerations
Configured Commerce is designed to be highly configurable and extensible to accommodate a multitude of business needs.
For example, an SAP ERP implementation stores customer data which includes organizational code. Configured Commerce does not include an organizational code on customer records. Therefore, there is a need to extend the Configured Commerce customer entity to map ERP properties to Configured Commerce properties.
Extension options
Configured Commerce has two ways in which to extend the entities within the platform. This can be done one of the following ways:
- Using the Application Dictionary
- Using Configured Commerce .NET objects and methods
Use the application dictionary
The entities that define the blueprint of the digital commerce objects needed to operate the platform can be extended using the Admin Console. Additionally, security permissions for fields are also managed from the Application Dictionary. Extending entities within the Admin Console provides a means to enrich the commerce objects with additional data. These fields, or properties, are then populated using any of the following ways:
- Users of the Admin Console
- Developers using Configured Commerce .NET objects and methods
- Configuration of Integration jobs
📘 Note Only basic types such as Boolean and Strings can be stored using application dictionary control types.
Use Configured Commerce .NET objects and methods
Custom properties can also be defined using code. This is usually done within a Handler of the Chain of Responsibility. Defining custom properties in code has the added advantage of storing complex types such as developer defined objects. The limitation here is that those custom properties cannot be edited within the Admin Console.
Use custom properties
From an implementation perspective, custom properties are stored as string values separate from the standard Configured Commerce objects, like Customer and Product. This flexibility in structure allows you to store a wide range of content, but can also cause a loss in application performance. Before using a custom property to store data, you should make the following considerations regarding the data and be certain that a custom property is the solution.
- Does the data need to be managed in Configured Commerce? Does it need to be displayed in the Storefront or should the data only be managed in the ERP or PIM? If the data is not required as described above, you should consider not storing it in the platform and keeping it in an external system.
- Does Configured Commerce provide a standard property that can store this data? Each Configured Commerce object provides quite a few properties and by default, some of them are not visible in the Admin Console. You can view them by enabling Master Edit Mode from the Debug Tools menu. Once that mode is enabled, you will see more properties displayed on the various detail pages.
- If a standard property cannot be found, can the data be stored on one of the standard properties that is not currently in use? This might seem odd, but there may be standard properties not currently being used. If you find a standard property with the correct data type, you could store the data in that property. The name of the property won't match the data, but the performance benefits could outweigh the inconsistency.
Custom properties may still be the correct solution. If this is the case and you start to see performance degrading for requests that retrieve those custom properties, you should consider creating a custom endpoint. The endpoint could be used to return only the custom properties you actually need. For example, on the product detail page, you could have a request that retrieves custom properties for that product. This request would be separate from the main product API request that retrieves the product data. If this solution does not work, you could consider creating a custom database table to store the custom properties. The table could be designed specifically for those custom properties, rather than having a table full of string values.
Always consider the need for custom properties. They are a useful and flexible feature, but they can also cause a loss in application performance. Other solutions are available to help offset this loss.
Database schema
The following tables are used for extending the entities and objects within Configured Commerce. Specifically these tables represent the schema used for custom properties and security. These entities are managed using the Configured Commerce Application Dictionary.
