Function import is not unique for actions

[#1]

I am playing around with RAP so I created some demo app. I defined root entity ZIS_I_Training and projection of it in ZIS_C_Training.

Here is the definition of these entities

define root view entity ZIS_I_Training
 as select from zis_a_training as Training
 composition [0..*] of ZIS_I_Participant as _Participant
 composition [0..*] of ZIS_I_TrainingTask as _Task
 association [1..1] to ZIS_I_Status as _Status on $projection.Status = _Status.Status
{
 @ObjectModel.text.element: ['Name']
 @Search.defaultSearchElement: true
 key training_uuid as TrainingUuid,
 @Search.defaultSearchElement: true
 name as Name,
 @Search.defaultSearchElement: true
 @ObjectModel.foreignKey.association: '_Status'
 @Consumption.valueHelpDefinition: [{entity:{name: 'ZIS_I_Status', element: 'Status' }}]
 status as Status,
 valid_to as ValidTo,
 created_by as CreatedBy,
 created_at as CreatedAt,
 last_changed_by as LastChangedBy,
 last_changed_at as LastChangedAt,
 local_last_changed_at as LocalLastChangedAt,
 /* Associations */
 _Participant,
 _Status,
 _Task
}

Here is the projection:

@EndUserText.label: 'Training projection view'
@AccessControl.authorizationCheck: #NOT_REQUIRED
@Metadata.allowExtensions: true
@Search.searchable: true
define root view entity ZIS_C_Training
 provider contract transactional_query
 as projection on ZIS_I_Training
{
 @Search.defaultSearchElement: true
 key TrainingUuid,
 @Search.defaultSearchElement: true
 Name,
 @Search.defaultSearchElement: true
 @ObjectModel.text.element: ['StatusText']
 Status,
 ValidTo,
 @Search.defaultSearchElement: true
 CreatedBy,
 CreatedAt,
 LastChangedBy,
 LastChangedAt,
 LocalLastChangedAt,
 _Status._Text.StatusText as StatusText : localized,
 _Participant : redirected to composition child ZIS_C_Participant,
 _Task : redirected to composition child ZIS_C_TrainingTask,
 _Status 
}

I think that definition of associated entites is not relevant for the problem, so I will not write it here.

I wanted to check how would it be possible to grab the input from the user described in the Blog post, so I introduced new action extendValidity and defined behavior for the interface entity as follows:

managed implementation in class zbp_is_i_training unique;
strict ( 2 );
define behavior for ZIS_I_Training alias Training
persistent table zis_a_training
lock master
authorization master ( instance )
etag master LocalLastChangedAt
{
 create;
 update;
 delete;
 association _Participant { create; }
 association _Task { create; }
 action extendValidity parameter ZIS_I_TrainExtend result [1] $self;
 field ( numbering : managed, readonly ) TrainingUuid;
 field ( readonly ) CreatedBy, CreatedAt, LastChangedBy, LastChangedAt, LocalLastChangedAt;
 field ( mandatory ) Name;
 determination setInitialValues on modify { create; }
 determination setReadFieldOnChange on save { field Name; field Status; }
 mapping for zis_a_training
 {
 TrainingUuid = training_uuid;
 Name = name;
 Status = status;
 ValidTo = valid_to;
 CreatedBy = created_by;
 CreatedAt = created_at;
 LastChangedBy = last_changed_by;
 LastChangedAt = last_changed_at;
 LocalLastChangedAt = local_last_changed_at;
 }
}

and the projection

projection;
strict ( 2 );
define behavior for ZIS_C_Training alias Training
use etag
{
 use create;
 use update;
 use delete;
 use action extendValidity;
 use association _Participant { create; }
 use association _Task { create; }
}

The problem is that I am getting following error after I enter date in the popup window and confirm input.

Error is: Function import 'extendValidity' is not unique for actions ZIS_I_TRAINING-EXTENDVALIDITY and ZIS_C_TRAINING-EXTENDVALIDITY

What should be the reason for this?

andre.fischer do you maybe have a hint?

Which release are you working on ?
SAP BTP ABAP Environment or SAP S/4HANA on premise (e.g. 2022) ?
