Here, we are going to explain the creation of custom SAP UI5 application using BOPF consumed OData service.

Pre-requisite– Please visit our previous blog posts for overview of the functionality and for the back-end creation.

Develop Draft Capable Custom Apps Using BOPF Framework – Part2

In this application, we have implemented the basic functionality like user can read/create/edit/delete the sales order header data along with durable locking and drafting functionality.

Let’s start the development of SAP UI5 custom application:

1.First step is to create destination in SAP Cloud Connector.

• Login to the SAP Cloud connector.
• Click on “Cloud to On-Premise” in SAP Cloud Connector and make an entry for the SAP system.

2.Next is to create destination in SAP cloud platform.

• Login to the SAP Cloud Platform (Neo Trial account) -> Destinations -> Click on “New Destination” -> Make a new entry and Check the connection.
• Connection should be reachable.

3.Then, open SAP WEB IDE Full Stack

•  And Click on “File” -> New -> Project from template -> “SAP UI5 Application” template -> Next

Note: Click on “Service tab” and enable SAP WEB IDE Full Stack service if not enabled.

• Enter Project Name and Namespace -> Click on “Next” then select View Type as XML and enter view name (HomePage) ->Click on “Finish”.

After this you can see the newly created project in files section.

4.Then right click on the project and add your OData service as displayed in the below picture.

•  Choose system in “Service Catalog” and search for the OData service (ZC_SALESORDERSHEAD_CDS)->next->finish.

Now, the next step is screen/view designing.

In our homepage/first view, we have added a smart table to display sales order header details and on the table header itself, we have added buttons for create and delete. And on the click of line item of the table, we have given the edit functionality. RadioButton is used to enable delete button which means on the click of radiobutton, delete button will enable.

                                                 HOME PAGE SCREEN

1. HomePage:  View1.view.xml

Note: Please see the comments in the code for better understanding of the view functionality.

For edit and create functionality, we are loading fragments here.

2.  Edit Screen: edit.fragment.xml

Note: ShareModel contains changes being done in Edit fragment.

Next, we had added a formatter file to set different kind of draft status to sales order.

4. Formatter.js

Here, statusText is a function which is used for setting draft status for sales order.

Types of draft status:

• Draft
• This object contains unsaved changes for user
• This object is locked by user

sap.ui.define([], function () {
	"use strict";
	return {
		statusText: function (DraftUUID,salesorder) 
		{
	 if (DraftUUID !== "00000000-0000-0000-0000-000000000000")
	{
		return "Draft";
	}
	
	if(salesorder !== "")
	{
		var oModel1 = new sap.ui.model.json.JSONModel();
		oModel1.loadData("/sap/opu/odata/sap/ZC_SALESORDERSHEAD_CDS/ZC_SalesOrdersHead(salesorder='"+salesorder+"',DraftUUID=guid'00000000-0000-0000-0000-000000000000',IsActiveEntity=true)?$expand=DraftAdministrativeData",null,false);
		
		if(oModel1.getData().d.DraftAdministrativeData !== null)
		{
	var flaglastchange = oModel1.getData().d.DraftAdministrativeData.DraftIsLastChangedByMe;
	var flagprocess = oModel1.getData().d.DraftAdministrativeData.DraftIsProcessedByMe;
	if (flaglastchange === false && flagprocess === false){
		var lockuser;
		if(oModel1.getData().d.DraftAdministrativeData.InProcessByUser === ""){
			lockuser = oModel1.getData().d.DraftAdministrativeData.LastChangedByUser;
	return "This object contains unsaved changes for user : " + lockuser;
		}
     	}	
	if(oModel1.getData().d.DraftAdministrativeData.InProcessByUser !== "")
	{
		lockuser = oModel1.getData().d.DraftAdministrativeData.InProcessByUser;
	    return "This object is locked by user : " + lockuser;
	}
	
		}
	}
		}
	};
});

Controller

Main view controller:  View1.controller.js

Function used:

onCreate function

• onCreate function is called on click of create button through View1.view.xml.
• onCreate opens Create fragment as dialog.
• Validation given for Input Fields in create.fragment.xml

onRegister Function

• onRegister function gets called on click of Create Button through Create fragment.
• Overall Status , Business Partner Id , Sales Document Type are mandatory when changes                  being saved on backend.
• POST ZC_SalesOrdersHeadPreparation is called to create draft data.
• POST ZC_SalesOrdersHeadActivation is called to convert draft to active data.

pressed function

• Function get called at the click of table’s line item.
• Here, we are setting cancel and discard button based on the draft created or not.
• Edit.fragment.xml is opened as dialog.
• checks if salesorder is not locked then error.
• checks if salesorder has unsaved changes then warning.
• else open edit.fragment.xml is opened as dialog.

onSubmit function

• onSubmit function is called on click of Save Button through Edit Fragment.
• Validation of mandatory fields at saving function ie Bussiness Partner ID,Overall Status,Sales            Document Type.
• Error “Please do some changes to be saved” is given when no change is performed on click of save button.
• POST ZC_SalesOrdersHeadPreparation is called to create draft data.
• POST ZC_SalesOrdersHeadActivation is called to convert draft to active data.

onchangecreate function

• onchangecreate is triggered on every live change in particular input fields in Create.fragment.xml

Input Fields:

• Overall status
• Business partner id
• Sales Document Type
• Sales Organisation
• Sales Group
• Cost Center
• Sold To Party
• Material
• Plant

Here, both post and merge operations performed.

• POST ZC_SalesOrdersHead
• MERGE                          ZC_SalesOrdersHead(salesorder=’salesorderno’,DraftUUID=guid’xyz’,IsActiveEntity=false

xyz is draftguid.

Here, if draft is not created ,create a new draft and merge livechanges to newly created draft.

and if draft already exists ,merge livechanges to already to existing draft.

onDelete function

• Delete function will be called on click of delete button in View1.
• REMOVE ZC_SalesOrdersHead(salesorder=’salesorderno’,DraftUUID=guid’xyz’,IsActiveEntity=false is called;

Here, xyz is draftguid.

onchangeedit function

• onchangeedit is called on every live change in particular input fields in edit.fragment.xml.

POST ZC_SalesOrdersHeadEdit is called

MERGE ZC_SalesOrdersHead(salesorder=’salesorderno’,DraftUUID=guid’xyz’,IsActiveEntity=false is called;

• Here, xyz is draftguid .
• if draft is not created ,create a new draft and merge livechanges to newly created draft.
• if draft already exists ,merge livechanges to already to existing draft.

onTableSelectionChange function

• on Line selection through radio button enable delete button on screen.

onClose function

• Works for edit.fragment.xml
• If draft exist then delete the draft record and close the dialog.

REMOVE ZC_SalesOrdersHead(salesorder=’salesorderno’,DraftUUID=guid’xyz’,IsActiveEntity=false is called;

xyz is draftguid here.

onBeforeRebindTable function

• Filter applied on smart table

onRefreshMlstBtnPress function

• Refresh smart table

After performing all the steps, the application works in following ways :-

1.Select the radio button corresponding to the sales order and then the delete button will be enabled and on click of the button delete operation will be performed.

2.Select the record and update operation in edit sales order screen

Perform changes in edit screen

• on click of close button, edit sales order dialog box closes and draft created is visible

• on click of discard changes button,draft is deleted

• on click of save button ,draft is updated

3.On click of “+” button ,create sales orderscreen appears

Mandatory fields are maintained; Fill in sales order fields

• on click of close button, create sales order screen is closed and draft is displayed

• on click of discard changes button, draft is deleted

• on click of create button, new sales order is created

  States of salesorder

1.Normal Sales order

2.Draft for existing sales order using edit screen

3.Draft with no sales order no using create screen

4.A Locked  sales order

5.Unsaved changes for sales order

Conclusion-

In this blog we are able to develop a Draft capable custom app using BOPF Framework.

We hope you find this blog series interesting and helpful in understanding Durable Lock Concept and how to develop Draft capable custom application.

We would like to thanks Karan Bahl for supporting us throughout the POC.

Have a great learning ahead.

Thanks,
