Delete OData Entities with the SAP Cloud SDK's Virtual Data Model

Start by creating a new file called delete-business-partner-address-route.ts and copy the following code into it:

import { Request, Response } from 'express';
import { BusinessPartnerAddress } from '@sap/cloud-sdk-vdm-business-partner-service';

export function deleteBusinessPartnerAddressRoute(req: Request, res: Response) {
  deleteBusinessPartnerAddress(req.params.id, req.params.addressId)
    .then(() => {
      res.status(200).send('Entity successfully deleted!');
    })
    .catch(error => {
      res.status(500).send(error.message);
    })
}

function deleteBusinessPartnerAddress(businessPartnerId: string, addressId: string): Promise<void> {
  return Promise.resolve();
}

This follows the implementation in the previous tutorials. deleteBusinessPartnerAddress does not do anything useful yet, but you will implement it in the next step. Now open application.ts, import the function and add the following route definition:

import { businessPartnerRoute } from './business-partner-route';
import { singleBusinessPartnerRoute } from './single-business-partner-route';
import { createBusinessPartnerAddressRoute } from './create-business-partner-address-route';
import { updateBusinessPartnerAddressRoute } from './update-business-partner-address-route';
import { deleteBusinessPartnerAddressRoute } from './delete-business-partner-address-route';

// ...

private routes(): void {
  const router = express.Router();

  router.get("/", indexRoute);
  router.get("/hello", helloWorld);
  router.get("/business-partners", businessPartnerRoute);
  router.get("/business-partners/:id", singleBusinessPartnerRoute);
  router.post("/business-partners/:id/address", createBusinessPartnerAddressRoute);
  router.put("/business-partners/:id/address/:addressId", updateBusinessPartnerAddressRoute)
  // add the following line
  router.delete("/business-partners/:id/address/:addressId", deleteBusinessPartnerAddressRoute)
  this.app.use("/", router);
}

Start by creating a new file called delete-business-partner-address-route.js and copy the following code into it:

const { BusinessPartnerAddress } = require('@sap/cloud-sdk-vdm-business-partner-service');

function deleteBusinessPartnerAddressRoute(req, res) {
  deleteBusinessPartnerAddress(req.params.id, req.params.addressId)
    .then(() => {
      res.status(200).send('Entity successfully deleted!');
    })
    .catch(error => {
      res.status(500).send(error.message);
    })
}

module.exports.deleteBusinessPartnerAddressRoute = deleteBusinessPartnerAddressRoute;

function deleteBusinessPartnerAddress(businessPartnerId, addressId) {
  return Promise.resolve();
}

This follows the implementation in the previous tutorials. deleteBusinessPartnerAddress does not do anything useful yet, but you will implement it in the next step. Now open application.js, import the function and add the following route definition:

const { businessPartnerRoute } = require('./business-partner-route');
const { singleBusinessPartnerRoute } = require('./single-business-partner-route');
const { createBusinessPartnerAddressRoute } = require('./create-business-partner-address-route');
const { updateBusinessPartnerAddressRoute } = require('./update-business-partner-address-route');
const { deleteBusinessPartnerAddressRoute } = require('./delete-business-partner-address-route');

// ...

private routes() {
  const router = express.Router();

  router.get("/", indexRoute);
  router.get("/hello", helloWorld);
  router.get("/business-partners", businessPartnerRoute);
  router.get("/business-partners/:id", singleBusinessPartnerRoute);
  router.post("/business-partners/:id/address", createBusinessPartnerAddressRoute);
  router.put("/business-partners/:id/address/:addressId", updateBusinessPartnerAddressRoute)
  // add the following line
  router.delete("/business-partners/:id/address/:addressId", deleteBusinessPartnerAddressRoute)
  this.app.use("/", router);
}

Next, we use the VDM to delete a business partner address. Open delete-business-partner-address-route.ts and overwrite deleteBusinessPartnerAddress as shown below:

function deleteBusinessPartnerAddress(businessPartnerId: string, addressId: string): Promise<void> {
  return BusinessPartnerAddress.requestBuilder()
    .delete(businessPartnerId, addressId)
    .execute({
      url: 'https://my.s4hana.ondemand.com/'
    });
}

Next, we use the VDM to delete a business partner address. Open delete-business-partner-address-route.js and overwrite deleteBusinessPartnerAddress as shown below:

function deleteBusinessPartnerAddress(businessPartnerId, addressId) {
  return BusinessPartnerAddress.requestBuilder()
    .delete(businessPartnerId, addressId)
    .execute({
      url: 'https://my.s4hana.ondemand.com/'
    });
}
