[Fiori Elements] Custom Column in a Table is not visible

December 11, 2023 December 12, 2023

I had a generated Fiori Elements App (done by using @sap/generator-fiori), containing a List, where I needed to add a custom column containing a Button. I found this well explained in the official documentation:

https://sapui5.hana.ondemand.com/#/topic/d525522c1bf54672ae4e02d66b38e60c

I followed the instructions exactly, but it didn’t work. When comparing my manifest.json again with the example, I noticed one minor difference. In my generated App, there was an extra items/ in front of the @com.sap.vocabularies.UI.v1.LineItem.

After removing items/ the custom column was suddenly visible. When I noticed the difference, I thought that would never be the reason. Luckily, I tested it after all. That really is a big problem with Fiori Elements. These are problems that can no longer be solved by debugging or similar.

Here some more helpful links, when challenging with a custom column:

[SuccessFactors] OData V2 – filter in (VSC Rest-API Client)

October 30, 2023 October 30, 2023

When filtering an OData V2 endpoint, you can simply list your values separated by a comma after the keyword in (option 2). Much shorter than having to repeat your filter statement all the time, like in option 1.

@user1=10010
@user2=10020

### Option 1: Filter userId using OR condition
GET {{$dotenv api_url}}/odata/v2/User?$filter=userId eq '{{user1}}' or userId eq '{{user2}}'
Authorization: Basic {{$dotenv api_auth}}
Accept: application/json

### Option 2: Filter userId using IN condition
GET {{$dotenv api_url}}/odata/v2/User?$filter=userId in '{{user1}}', '{{user2}}'
Authorization: Basic {{$dotenv api_auth}}
Accept: application/json
