SAP RAP Fiori Elements Object Page Multi-Input Dropdown

[abhiperiwal]

Hi,

I am looking for help to create a multi-input combo box on a Fiori elements Object page created using RESTFul ABAP.

I'm following the instructions provided in the below link:

Using the Multi-Input Field on the Object Page - Documentation - Demo Kit - SAPUI5 SDK

I understand that I need to define a composition to the entity which is required to be displayed in the multi-input control. However, if I define the composition, I also have to define a to-parent relationship in the child entity which can be done only on the key of the parent. In my case the parent's key field is a GUID value which cannot be specified in the entity for multi-input control. 

More details of my example:

1. The multi-input field is required for an entity with possible Values. I have defined as below:

define view entity Z_I_NameValues
as select from ...
composition [1..*] of Z_I_Value as _Values2.

2. The parent entity's key field is GUID, but there are other fields such as Name and Value. Multi-Input dropdown is needed on the field Value.

3. Definition of value help child entity Z_I_Value:
define view entity Z_I_Value
as select from ...
{ key Name, key Value} 

How do I define the parent-child entity relationship to display the Value field as multi-input value?

Thanks,

Abhishek
