How to open a business object in Edit mode using a custom action/button via RAP/Fiori Elements?

[rammel_sapdev]

Hi,

Is there a way to open the business object in Edit mode after clicking a custom action (e.g., Reset button)? The reset button currently has 2 purposes, first is to clear the screen and the other is to open the object in Edit Mode (i.e., Draft State).

I know that we can simply click the Edit button and subsequently click Reset button or vice versa, we are just wondering if it is feasible to do it in a single button click.

I tried applying the logic based on Ramjee's tutorial (https://community.sap.com/t5/technology-blogs-by-members/abap-restful-application-programming-enabli...) but I am getting this error message (although in the background, the draft instance has been created):

I suspect it has something to do with the URL parameters:

Before clicking Reset button, the UNAME field is filled up with the username value which is the key for this business object.

&sap-client=100#/zc_fileupload(Uname='RBALAGTA',IsActiveEntity=true)

However, after clicking the Reset button (and refreshing the screen via side effects), the uname field became blank.

&sap-client=100#/zc_fileupload(Uname='',IsActiveEntity=false)

Here is my code for the Reset action implementation:

I have added also the behavior definition below.a

managed implementation in class zbp_i_fileupload unique;
strict ( 2 );
with draft;

define behavior for zi_fileupload alias Upload
with unmanaged save with full data
draft table zdfileupload
etag master uname
lock master
total etag uname
authorization master ( global )
{

  field ( readonly ) Uname, Input6;
  field ( mandatory ) Input1;
  internal create;
  update;
  delete;
  association _output { internal create; with draft; }
  association _Parameters { create; with draft; }

  action processRecords result [1] entity zi_fileupload;
  action (lock : none) resetScreen result [1] entity zi_fileupload;
//  action (lock : none) resetScreen;

  validation validateInput on save { create; update; }
  validation validateInput1 on save { create; field Input1; }
  validation validateAttachment on save { create; field Attachment; }

  determine action valdetInput1 { validation validateInput1; }
  determine action valdetAttachment { validation validateAttachment; }

  side effects {
    action resetScreen affects $self, entity _output;
    action processRecords affects entity _output;
    determine action valdetInput1 executed on field Input1 affects messages;
    determine action valdetAttachment executed on field Attachment affects messages;
  }

  draft action Edit;
  draft action Activate optimized;
  draft action Discard;
  draft action Resume;
  draft determine action Prepare
  {
    validation validateInput;
    validation ( always ) validateInput1;
    validation ( always ) validateAttachment;
  }

}

define behavior for zi_fileoutput alias Output
with additional save
persistent table zfilecontent
draft table zdfilecontent
lock dependent by _File
authorization dependent by _File
etag master uname
{
  internal update;
  internal delete;
  action processData result [0..*] $self;
  field ( readonly ) uname, sequence;
  association _File { with draft; }

  side effects {
    action processData affects $self;
  }
}

define behavior for zi_uploadparams alias Parameters
with unmanaged save with full data
draft table zduploadparams
lock dependent by _File
authorization dependent by _File
etag master uname
{
  internal update;
  internal delete;
  field ( readonly ) uname, sequence;
  association _File { with draft; }
}

@Ramjee_korada, maybe you can help. I tried to post this question as a comment to your original post but it was marked as spam, probably after I edit it multiple times.

Any luck? Even I have same scenario.
