Dropdown List in Fiori Elements

Adding a dropdown list in a Fiori Element based app is somewhat tricky before. We had a requirement in our project and have checked all these blogs, and one could normally find the solution as redefining the method of class MPC_EXT, as mentioned in the blog

https://blogs.sap.com/2016/04/16/how-to-build-a-drop-down-list-using-smart-template-cds-view/#jive_content_id_Step1_Create_a_simple_CDS_view_to_hold_status_code_and_status_description

But we can simply achieve this with an annotation.

@ObjectModel.resultSet.sizeCategory: #XS

 

Most of you might know how to use this, anyways I shall just explain it for a quick understanding for newbies.

Here we are bringing the dropdown list as a filter in a List Report.

Add the mentioned annotation in the CDS which will be consumed as a valueHelp for the respective filter in List Report.

 

Association is added in the Main CDS where the above CDS is consumed.

Valuehelp is assigned inside select.

 

Mentioned as selectionField in  Metadata Extension. This can be mentioned in CDS also as shown above.

 

Generate application and Execute. The filter field is displayed as Dropdown List.

      Same for me. I followed the simple instruction and it doesn’t work ?

      I’m using Web IDE of SCP… Obvioulsy latest version of SAP UI5 lib.

      I have a nice liveSearch result when I enter something but no Dropdown.

      Thanks for any advice,

      Luc

      the annotation (@ObjectModel.resultSet.sizeCategory:#XS ) works only starting from NW 7.52 version for S/4HANA – version 7.51 does not support this annotation

      Hi Vladyslav,

      Thanks for your answer. I'm working on SAP Web IDE and deploying on SCP. The current version is 1.64. You means that I need S/4Hana and not only SCP ?

      Hi Vladyslav,

      Thanks now I got my mistake...

      The UI annotations of the CDS View are calculated (rigth word ?) with SADL (is it true) of the Backend system, not the Gateway/SCP one...

      In our case, we are in 7.50. That's crystal clear 🙂

      Hello.

      I want to show more than 100 entries in the drop-down list.
      I've tried this: @ObjectModel.resultSet.sizeCategory: #S
      Unfortunately, no success.
      The annotation ObjectModel.resultSet.sizeCategory expects a String(3), but #S has the length 2.

      Can someone help me there?
