[ABAP] JSON to ABAP with dereferencing

Recently I had to fetch an attachment from SuccessFactors. The API returns a huge JSON. Here only a few lines of that json.

Parsing the JSON to ABAP

SAP provides two classes /ui2/cl_json and /ui2/cl_data_access to work with JSONs and there are also many cool tools on https://dotabap.org/ for that.
Because it’s just a simple JSON I tried to avoid importing another class to the system. So I stayed with SAPs classes.

First deserialize the JSON with /ui2/cl_json.

    " Constants for properties
    CONSTANTS gc_filecontent TYPE string VALUE 'FILECONTENT' ##NO_TEXT.
    CONSTANTS gc_filename    TYPE string VALUE 'FILENAME' ##NO_TEXT.
    CONSTANTS gc_doc_cat     TYPE string VALUE 'DOCUMENTCATEGORY' ##NO_TEXT.
   
    DATA: lr_data TYPE REF TO data.
    /ui2/cl_json=>deserialize( EXPORTING json = lv_responce  "the repsonse contains the json string
                               CHANGING  data = lr_data ).

I found three similiar ways to use the class /ui2/cl_data_access to get the relevant data out of the JSON.

1. Using the class construktor and the value( ) method for earch property.

    DATA: lv_filecontent_base64 TYPE string,
          lv_filename           TYPE string,
          lv_documentcategory   TYPE string.

    /ui2/cl_data_access=>create( ir_data = lr_data iv_component = |D-{ gc_filecontent }| )->value( IMPORTING ev_data = lv_filecontent_base64 ).
    /ui2/cl_data_access=>create( ir_data = lr_data iv_component = |D-{ gc_filename    }| )->value( IMPORTING ev_data = lv_filename).
    /ui2/cl_data_access=>create( ir_data = lr_data iv_component = |D-{ gc_doc_cat     }| )->value( IMPORTING ev_data = lv_documentcategory ).

2. Create an instance as first step and pass the component. Reuse the instance with the value( ) method.

    DATA: lv_filecontent_base64 TYPE string,
          lv_filename           TYPE string,
          lv_documentcategory   TYPE string.

    DATA(lo_data_access) = /ui2/cl_data_access=>create( ir_data      = lr_data
                                                        iv_component = |D-| ).
    
    lo_data_access->at( |{ gc_filecontent }| )->value( IMPORTING ev_data = lv_filecontent_base64 ).
    lo_data_access->at( |{ gc_filename    }| )->value( IMPORTING ev_data = lv_filename ).
    lo_data_access->at( |{ gc_doc_cat     }| )->value( IMPORTING ev_data = lv_documentcategory ).

3. Use the ref( ) method to get a reference of a property value. Because it returns a generic data type (and you cannot dereference generic references) you have to use CAST combined with dereferencing (->*) the get the concret value.

    DATA(lo_data_access) = /ui2/cl_data_access=>create( ir_data      = lr_data
                                                        iv_component = |D-| ).

    DATA(lv_filecontent_base64) = CAST string( lo_data_access->at( gc_filecontent )->ref( ) )->*.
    DATA(lv_filename)           = CAST string( lo_data_access->at( gc_filename    )->ref( ) )->*.
    DATA(lv_documentcategory)   = CAST string( lo_data_access->at( gc_doc_cat     )->ref( ) )->*.

In the end I stayed with version 3 because I prefere using inline declarations. The complete result looked like this:

    " Constants for properties
    CONSTANTS gc_filecontent TYPE string VALUE 'FILECONTENT' ##NO_TEXT.
    CONSTANTS gc_filename    TYPE string VALUE 'FILENAME' ##NO_TEXT.
    CONSTANTS gc_doc_cat     TYPE string VALUE 'DOCUMENTCATEGORY' ##NO_TEXT.

    DATA: lr_data TYPE REF TO data.
    /ui2/cl_json=>deserialize( EXPORTING json = lv_responce  "the repsonse contains the json string
                               CHANGING  data = lr_data ).

    DATA(lo_data_access) = /ui2/cl_data_access=>create( ir_data      = lr_data
                                                        iv_component = |D-| ).

    DATA(lv_filecontent_base64) = CAST string( lo_data_access->at( gc_filecontent )->ref( ) )->*.
    DATA(lv_filename)           = CAST string( lo_data_access->at( gc_filename    )->ref( ) )->*.
    DATA(lv_documentcategory)   = CAST string( lo_data_access->at( gc_doc_cat     )->ref( ) )->*.

    " Decode BASE64 PDF to XString
    DATA(lv_decodedx) = cl_http_utility=>if_http_utility~decode_x_base64( lv_filecontent_base64 ).
    " XString to binary
    DATA(lt_data)     = cl_bcs_convert=>xstring_to_solix( lv_decodedx ).

    " Download file
    cl_gui_frontend_services=>gui_download( EXPORTING bin_filesize         = xstrlen( lv_decodedx )
                                                      filename             = lv_filename
                                                      filetype             = 'BIN'
                                                      show_transfer_status = ' '
                                             CHANGING data_tab             = lt_data ).

[SAP] Difference between Platform Users and Business Users

Platform users are usually developers, administrators or operators who deploy, administer, and troubleshoot applications and services on SAP BTP.”

Business users use the applications that are deployed to SAP BTP. For example, the end users of your deployed application or users of subscribed apps or services, such as SAP Business Application Studio or SAP Web IDE, are business users.”

[SAPUI5] MyInbox: Integration of Detail View – EmbedIntoDetail

https://launchpad.support.sap.com/#/notes/2305401 (App to App Navigation CookBook.pdf)

https://blogs.sap.com/2020/07/31/fiori-my-inbox-integration-of-custom-detail-page/

Target:

Go to /n/ui2/fpld_cust and define a second target for your App, i.e. approve.

The approve target needs the “emdedIntoDetails” parameter:

SWFVISU:

Add the new target for your WF Task. Here you have access to all attributes of your Workitem-Container. Pass all your mandatory fields you’ve defined in your oData Entity.

Some examples: https://blogs.sap.com/2016/05/31/my-inbox-open-task-swfvisu-configuration/

If your missing some parameters, just add them in your Workitem Task and pass the values directly into it right from your Workflow Container. This looks much better.

Manifest:

Add a route to navigate via Inbox. The pattern has to match your inbox url.

			"routes": [
				{
					"pattern": "",
					"name": "master",
					"target": "master"
				},
				{
					"pattern": "DataSet/{Pernr},{Datum},{Infty}",

					"target": [
						"master",
						"object"
					]
				},
				{
					"pattern": "detail/LOCAL_INBOX/{wfInstanceId}/{taskPath}",
					"name": "wfobject",
					"target": "object"
				}

Detail.Controller:

	onInit: function () {
			// Model used to manipulate control states. The chosen values make sure,
			// detail page is busy indication immediately so there is no break in
			// between the busy indication for loading the view's meta data
			var oViewModel = new JSONModel({
				busy: false,
				delay: 0
			});

			this.getRouter().getRoute("object").attachPatternMatched(this._onObjectMatched, this);

			//My Inbox Integration
			this.getRouter().getRoute("wfobject").attachPatternMatched(this._onWFObjectMatched, this);

			this.setModel(oViewModel, "detailView");

			this.getOwnerComponent().getModel().metadataLoaded().then(this._onMetadataLoaded.bind(this));

		},


		_onWFObjectMatched: function (oEvent) {
			this.getModel("appView").setProperty("/layout", "MidColumnFullScreen");
			var compData = this.getOwnerComponent().getComponentData();

			if (compData && compData.startupParameters && compData.startupParameters.PERNR && Array.isArray(compData.startupParameters.PERNR) &&
				compData.startupParameters.PERNR[0]) {

				var sPernr = compData.startupParameters.PERNR[0];
				var sDatum = compData.startupParameters.DATUM[0];
				var sInfty = compData.startupParameters.INFTY[0];

				this.byId("detailPage").addStyleClass("myInboxPage");

				this.getModel().metadataLoaded().then(function () {
					var sObjectPath = this.getModel().createKey("/DataSet", {
