Dengan menggunakan tugas Pemetaan Data, lakukan iterasi pada elemen array string dan terapkan fungsi transformasi untuk mengonversi setiap nilai string menjadi huruf besar.
Klik Integrations dari menu navigasi sebelah kiri untuk membuka halaman Integrations.
Pilih integrasi yang ada atau buat integrasi baru dengan mengklik Buat integrasi.
Jika Anda membuat integrasi baru:
Masukkan nama dan deskripsi dalam dialog Buat Integrasi.
Pilih region untuk integrasi.
Pilih akun layanan untuk integrasi. Anda dapat mengubah atau memperbarui detail akun layanan integrasi kapan saja dari panel infoRingkasan integrasi di toolbar integrasi.
Klik Buat.
Tindakan ini akan membuka integrasi di editor integrasi.
Di editor integrasi, klik publishmenu Upload/download, lalu pilih Upload integrasi.
Dalam dialog file browser, pilih file yang Anda simpan di langkah 1, lalu klik Open.
Versi baru integrasi dibuat menggunakan file yang diupload.
Di editor integrasi, klik Uji.
Klik Uji integrasi. Tindakan ini akan menjalankan integrasi dan menampilkan hasil eksekusi di panel Test Integration.

In the Google Cloud console, go to the **Application Integration** page.\n\n [Go to Application Integration](https://console.cloud.google.com/integrations)\n3. Click **Integrations** from the left navigation menu to open the **Integrations** page.\n4. Select an existing integration or create a new integration by clicking **Create integration** .\n\n\n If you are creating a new integration:\n 1. Enter a name and description in the **Create Integration** dialog.\n 2. Select a region for the integration. **Note:** The **Regions** dropdown only lists the regions provisioned in your Google Cloud project. To provision a new region, Click **Enable Region** . See [Enable new region](/application-integration/docs/enable-new-region) for more information.\n 3. Select a service account for the integration. You can change or update the service account details of an integration any time from the info **Integration summary** pane in the integration toolbar. **Note:** The option to select a service account is displayed only if you have enabled integration governance for the selected region.\n 4. Click **Create**.\n\n\n This opens the integration in the *integration editor*.\n5. In the *integration editor* , click publish**Upload/download menu** and then select **Upload integration**.\n6. In the file browser dialog, select the file that you saved in step 1, and then click **Open** .\n\n A new version of the integration is created using the uploaded file.\n7. In the *integration editor* , click **Test**.\n8. Click **Test integration** . This runs the integration and displays the execution result in the **Test Integration** pane."]]
