About #

This article leads you through all necessary steps to set up the following process in Nintex for Office 365:

  • When an SAP material number is entered in an input field, the possible hits are displayed in a dropdown list.
  • If a material is selected in the drop-down list, the material text is displayed in a text field.
  • When the input is confirmed, the selected material is written to SharePoint.

Integrating JavaScript Code in Nintex #

The JavaScript library for REST services by Theobald Software enables the use of yunIO services via JavaScript.
The depicted example uses the following JavaScript code for the following:

  • To import the JavaScript library for REST services.
  • To connect to yunIO.
  • To run the service “MAKTService” that reads the material number and the material long text from the SAP table MAKT.
document.addEventListener("DOMContentLoaded", async () => {
    let yunioClient = await import(
        "https://static.theobald-software.com/theobald.yunio.client.js/dist/theobald.yunio.client.js"
    );

    yunioClient.TheobaldYunioClient.initializeLiveCombobox({
        $: NWF$,
        controls: {
            inputId: inputMaterial,
            selectId: selectMaterial,
            outputId: outputMaterialId
            /*descriptionId: outputMaterialDescription*/
            /*buttonId: 'buttonId'*/
        },
        tableSettings: {
            serviceName: "MAKTService",
            idField: "MATNR",
            description field: "MAKTX",
            language: "E"
        },
        connection: {
            url: "https://yunio.example.com:8175/",
            /* future apiKey */
            username: prompt("yunIO username", ""),
            password: prompt("yunIO password", "")
        }
    });
});

Note: To use this script in your application, replace the connection URL. If your yunIO service has a different name or settings, edit the table settings accordingly.

Follow the steps below to integrate the script in your Nintex Form:

  1. Open the settings of the Nintex form and copy the JavaScript into the field Custom JavaScript. nintex-office-java-code
  2. Click [Save].

Running the Nintex Form #

  1. Preview or publish the Nintex form.
  2. When prompted, enter your username and password to establish a connection to yunIO.
  3. Enter a material number. The hits for the entry are read from SAP and displayed in the dropdown list “Suggested Materials”.
  4. Select a material from the dropdown list. The long text of the selected material is displayed in the field “Material”.
  5. Click [Save] to write the selected material to your SharePoint custom list.
