- I am currently want to develop POC on UI5 application with OData from ASE 15.7 developer edition instead of SAP Netweaver Gateway.
- It is easy to configure ASE with OData on laptop (Win 7) and UI5 app. development for POC.
I discovered this issue, fields which have Foreign Key relationship is not included in metadata and as well output data (atom/xml or json)
Database "odata" and table 'SalesOrders' which is taken from "dotnet" example (\Sybase\ODATA-16_0\samples\dotnet\init.sql)
| Column_name | Type | Length | Foreign Key |
| ID | int | 4 | |
| CustomerID | int | 4 | Employees.EmployeeID |
| OrderDate | date | 4 | |
| FinancialCode | char | 2 | FinancialCodes.Code |
| Region | char | 7 | |
| SalesRepresentative | int | 4 | Customers.ID |
Starting OData service for database "odata"
cmd> cd %sybase%\ODATA-16_0\samples\dotnet
cmd> ..\..\bin64\dbosrv16 DotNetConfig.properties
Metadata Service document --> missing properties CustomerId, FinancialCode and SalesRepresentative which are all fields has Foreign Key defined in the Table level
