This blog is on continuation to Part 1.
In this part we shall create the BOPF action and display the sale order scenario in the Fiori App using Smart Template.
For the BOPF action, go to BOPF Business Object ZDEMO_I_SALESORDER from Tcode BOBX. Click on change mode. Under the Node Elements, traverse to node ZDEMO_I_SALESORDER and select Action element. Right Click on Action and Click "Create".
Go to Class Builder and create the class ZCL_A-DEMO_SALESORDER.
Implement the method Execute.
Save and Activate. The code can be found in the attachment. Basically the code reads the selected sales order and then change the corresponding BOPF node instance with the new lifecycle status value.
Okay we are done with all the backend stuff.
Lets display this using as Fiori App using Smart Template.
If all the Web IDE set up explained in Part 1 is fine, we can proceed. Go to Web IDE. Click on File.
Click on File --> New --> Project from template
On next screen, Select Service Catalog. Click on the dropdown and select your backend system.
Once the backend system is selected, OData services in the system are listed. Look for our OData generated service ZDEMO_C_SALESPRDER_CDS ie <final consump CDS view>_CDS
Select the Odata service. Click on Show details to check if the OData is up and running
Here we see the OData service is running fine.
Click on Next. In the Next screen the system will read and the OData service metadata file and also the CDS Annotations file(final consumption CDS). These are necessary to display the app.
The annotations in the final consumption CDS view (ZDEMO_C_SALESORDER) contain the UI line position which shall form the basis for field positioning in the app.
Click Next. In OData collection, select the consumption view(where OData was published). Our final consumption view has an association to Item. Hence here the OData navigation refers to "_item".
Click Next or Finish and its done !
The project name is visible under the workspace. Right click on the project. Click Run as -> Web Application
If prompted, choose flp sandbox.html. These are used to for test data basically.
Click Ok. If prompted, for login credentials, enter the backend system details. Finally the app icon is displayed in the Catalog Tile.
Click on the App. If prompted for the login credentials, enter the back-end system details.
Click on Go in the app to display the sales order records.
Select the record by selecting the radio button and clicking. The navigation happens to the detail screen.
Click on Edit. For example, lets update the Gross Amount and click on Save.
The Gross amount value is edited to 3500 INR. Click Save.
"Object saved" message appears. Go back to previous app page.
The new Gross amount is reflected here.
The Edit is excuted in BOPF via CDS and the particular BOPF node instance is edited. This is achieved as we have given the create/update/delete enabled in the final consumption CDS which delegates to the Basic CDS and then to BOPF.
Create a new record.
In the basic CDS ZDEMO_I_SALESORDER, we have maintained the annotation @objectmodel.create enabled: true which means the create logic is taken care by BOPF.
Click on + icon in the app to create a new sales header record.
Enter the values and click on Save.
An object saved message appears. The record is saved. Go to previous page and see the newly created record.
The delete icon works the same way. Just select an record and click on delete.
Change the sales order Lifecycle status
Select an sales order which has initial status and click on icon "Set Lifecycle Status to Paid". The code which we have written for the BOPF Action is triggered and the status is changed to P.
Lifecycle status has changed to P(Paid)
That's it. Hope this is helpful.
