Creating an inheritor of TrnProduct

Let's use the inheritance pattern to access a list of "cheap" Products (price ranging from 10 to 50€).

To do so, follow the steps below :

1. In the Business objects > Business objects menu, click Creation assistant

   For a detailed guide, see Add an object

2. Create a Business object :
   • Code : TrnProductCheap
   • Table : trn_product (the table is the same as the parent object's)
3. Click Next
4. Create a Translation for the object :
   • English : Cheap products|Cheap product
5. Grant a Read only function to the TRN_SUPERADMIN Group
6. Follow all the steps of the creation process
7. In the Extend of Logical name field of TrnProductCheap, select TrnProduct
   
8. Click More on the Objects form
   
9. Set the following value in the Filter field : trn_prd_price < 50
   
10. Click Save

Test the newly created inheritor with usertest

1. Clear the platform's cache and log in using usertest

   For a detailed step-by-step, see : Testing the User
