B1 Assistant – Retire your keyboard with SAP Business One and Alexa

B1 Assistant – Retire your keyboard with SAP Business One and Alexa: You’ve probably heard about a prototype we demo at the ASUG Summit in Miami. The proposal was to present how easy companies can embrace the digital economy transforming their business on daily tasks (if you haven’t seen that before, you are probably not following the right people on twitter).

A bit different from what some of you asked me, this is not a core feature of SAP Business One (I know, sad right? ☹️ ), it’s a prototype developed by the Solution Architects team, just like many others we shared before.

Good news the code is open for you to use and implement your own version. And here is a tutorial of how to install the B1 Assistant and “retire” your keyboard for some B1 tasks.

So, grab your popcorn, sit tight, follow me on twitter and enjoy this how-to!

I will not go into details of the Echo development capabilities. If you want to navigate on those waters, check their official ASK (Alexa Skill kit) site (very well made, simple and with great samples) and this detailed tutorial by Jarkko Lane. But one thing that should be clear for you is:

The Architecture

Alexa  (Amazon Echo’s persona) has several capabilities (Skills). Those are divided between Native (time, weather, traffic, news…) or 3rd Party (Uber, Spotify, Business One…)

To activate the 3rd party skill, we use Invocation Names. Those are nothing more than the name of the skill we want to call. For example: “Alexa, ask Uber for a ride” or “Alexa, open Spotify”. Once it hears your command, it will identify the skill to be triggered and call a specific Web Service that can be hosted on a Private Cloud or on AWS. Like this:

In our case, working the with B1 Assistant Skill the architecture is:
NOTE: On a productive scenario, we could bypass the AWS Lambda service and make Alexa communicates directly with HANA XS. That would require a secure HTTPs connection with a valid SSL Certificate. Thing we don’t have on most dev environment.

Skills details

Beside the Invocation Names, the skills have 2 other attributes, the intent, which is the specific action to be activated and the slots that works as parameters of the first one.

Implementing the B1 Assistant

Enough with definitions and small talk, let’s go for the funny part. So you can have your own B1 Assistant.


  • A SAP Business One on HANA 9.2 PL04 environment.
    • PL03 will also work, with limited features (No Prediction)
  • SBODEMOUS schema
    • To work with different schema, please adapt all models and procedures
  • An Amazon Developer account
  • An Amazon Web Services Account
  • An Amazon Echo (not mandatory, but pretty cool to demo)

All the code used in this tutorial is shared on github

1 – Deploying the B1 Assistant HANA app

We’ve seen that whenever a user asks Alexa , it will trigger a Skill, this skill will call a function and this function will interact with an application (SAP Business One)

So let’s build our stack, starting by the end. The B1 Assistant App on HANA.

There 2 options for this part:

  • You can import the b1Assistant application delivery unity into your HANA System
    • see how to import a delivery unity
  • Or just clone the code directly fromgithub and create your own XS project.

Whatever the case, once you have the b1Assistant package on your HANA system.
Go to HANA Administration Tools dashboard (https://hanaserver:8000/sap/hana/xs/admin) and set a user and password for the file: b1Assistant > lib > annonuser.xssqlcc

Note: Alexa will use this user to retrieve data and access the services.
You can also access https://hanaserver:8000/b1Assistant to test your app back-end

note: B1 user/pass is set on services/b1call.xsjs file

2 – Creating the B1 Assistant Lambda function


UPDATE August/2018 – Since SAP Cloud Platform adopted Cloud Foundry it is possible to deploy the “Lambda Function” (that is nothing more than a NodeJs script) on SAP CP. No changes are required on the code. And the steps to deploy it can be found in this video. There is also another deployment option to have the script running locally in a “stand alone” server. In this case an additional wrapper code is required and it is also in the github repository. Since both options are a bit more techy you will find the steps details on github

With the HANA App deployed, we need a function to call its services (Create orders, item recommendation, sales info). The responsible for it will be a Lambda Function.

Access your Amazon Web Services Account, switch to the Ireland or North Virginia region and select the Lambda Service.

Get started with a new Lambda function

On the blue print selection, search for Alexa and choose the skill tagged as alexa-skills-kit-color-expert

Select Alexa Skills Kit as a trigger

Set a name for your service, e.g b1Assistant and copy the code b1Assistant.js located on the skill folder (set your HANA Server public IP where indicated)

Scroll down a bit and set the following configurations just like the screenshot below

note: 15 sec timeout will avoid issues when B1 Service Layer takes long time to respond.

On the next step you have to opportunity to review all settings and then, create your function.

Once the function is created we need to extract it’s ARN address. It’s quite simple, just do as the following. And copy this address somewhere you can find later.

3 – Creating the B1 Assistant Skill

We are almost there, all that is missing is the Alexa Skill to talk to our Lambda Function.

Log into the Amazon Developer website and chose Alexa on the top menu

Get started with a new Alex Skill Kit

Add a new skill

On the Skill information panel, set the Skill Name – B1 Assistant and Invocation Name – B1 Assistant – Retire your keyboard with SAP Business One and Alexabe one.

On the next window you should fill the Intent Schema, Custom Slot Types and Sample Utterances
The codes are available on the Skill folder on my github repository

Save, Go to the next step and paste the ARN address extracted previously, according to the region of your Lambda funciton (US or Ireland)

On the next step you can already test your skill and see that it is ready to work

Your B1 Assistant is ready to work! You can test it with your Amazon Echo by enabling the Skill on your Alexa app or use the Echo Simulator.

Special Thanks to the SAP Business One dev team in Shanghai that helped us with the predictive analysis feature! You rock!


B1 Assisant got smarter!!

There is a very cool enchament on this prototype made by Yatsea Li, integrating it with the Twitter Sentiment App. If you want to give your B1 Assistant more powers, once you fisished this tutorial, follow the instructions in his blog
