SAP for Mobile: Why SMP and Why Not

Posted by Shrikant NaiduSep 3, 2013

Hi,

Recently, i was exploring few options for a giving up a solution architecture to one of my

customers who needs a mobile solution which gets synchronized with their SAP back-end

system. So i just thought to Blog it for my friends out here and i end up figuring out that there

are two major ways for doing this i.e,

1. Using SMP (SAP Mobile Platform)

2. Using JCo (Java Connector) i.e, without SMP.

So here are the advantages i figured out for both the approaches:-

Using SMP:

There are Native(Object API, ODATA) and Hybrid application(Html5 based) development approches. The

platfrom provides you to develop Hybrid applications easily by drag and drop.

You can integrate various backend systems easily so that you handle connectivity of systems.

Be able to create offline scenarios with SUP platform. (Native development)

You can model your data by creating relations, queries etc.. (MBO development)

Manage and monitor device users acitivity on Sybase Control Center

Enable you to configure SSO or Active directory.

Provides end to end security

Using JCo (Without SMP)

With Jco you can direclty access to RFC without using web services

Create only online scenarious.

You have to make development for each device(ios, android, win8)

That's all till now i figured out.

However this is an interesting question and if I understand it correctly we are basically trying

to understand here whether to use a middleware like SUP/SMP or not or perhaps just useanother middleware?

The question can only be answered through some analysis of requirements topics like the

following should point towards whether we should be using SUP/SMP or not:

Security

How sensitive is the data you are planning to mobilise and do you need the extra security mechanisms that

SUP/SMP brings ?

How do you plan on authenticating your users and will you be able to do that in a large scale roll-out

without a box like SUP/SMP in the middle.

Do you require on-device security enhancements to protect the data you transmit to a device.

Synchronisation

Are you planning on synchronising and storing data on the mobile devices and if so have you considered

how that sync will happen without a middleware to manage the sync process.

How do you plan on achieving the synchronisation between your devices and the back-end server

(protocols, packaging, parsing etc.)

Synchronization

Are you planning on synchronizing and storing data on the mobile devices and if so have you considered

how that sync will happen without a middleware to manage the sync process.

How do you plan on achieving the synchronisation between your devices and the back-end server

(protocols, packaging, parsing etc.)

Device management

Do you need the connection/device management brought by SUP/SMP

There are a lot of topics we would need to look at before we can make a decision on this

and we will not be able to get a clear answer here without completely understanding the

requirements and what we need to achieve. Its also worth looking at how we have delivered

other applications (if we have) in your environment including what worked/did not.

I still falls into this scenario again & again while proposing a solution to customers & always

exploring the right solution for it. However, i'd always like say Thanks to few of my friends

out here for always helping me out here like Midhun VP, Jitendra Kumar Kansal, Tahir

Oz, Brenton O'Callaghan, Carolyn Fitton , David Clavey , Rohith Deraje , Kevin Benedict ,

Thomas Jung

Off course there are other workarounds also available & i'd appreciate if you folks will

provide light on this here below

Good One Shrikant ..

Every time we get new requirement, we explore new solutions...

It is good experience to get into the requirement deeply, and find out the exact solution and

propose it.....

Thanks Shrutika Purohit.

Agree with U.

There is a big complexity while mobilizing the enterprise. SMP is meant to make the process

easy and secured. Few of the advantages of using SMP when compared without a middle-

ware are:

Device Heterogeneity - Supporting the rapidly expanding and changing selection of devices and device OS

on the market.

Data partitioning for mobile app - Separating and securing data storage. Encrypted data storage in the

device. It can be done in few lines of code/ automatically it will be provided by SMP.

Data transport and app security - Securing data while data transfer.

Bandwidth and latency an connectivity issues (important one) - Easy management of multiple connections,

easy synchronization methods, caching between EIS and devices. And allowing the users to work inalways connected, occasionally connected and some times connected environments.

Device and app management - this includes device upgrades, deployment of new apps, upgrades without

affecting production.

Apart from the above we don't want to bother about the security, logging, tracing, SSO ( in

few steps ).

So these are the reason to go with SMP/middle-ware.

Recently SAP released apps based on SAPUI5 ( FIORI series ) and it is not based on SMP.

Again, these apps are based on web technologies hence the performance we can't expect

as good as native apps.

Finally, selection of development approach is purely based on the available resource and

business requirement. If the company is planning to go mobile and the budget is low means

they can mobilize there process with NW gateway. They don;t need to spend on SMP.

So selection of a technology is based on the above factors and SAP is providing us the

completing set of solutions from which we can select a solution.

I would have a look at how the Fiori apps are created and add it to your second non-SMP

list. The big point about Fiori is that it uses ODATA via the Netweaver Gateway. So all the

security and data change is based on the Gateway.

I would not create a mobile app using JCO - Old technology. It will work fine, especially

if you are a Java on mobile fan. But Java on a mobile is all too slow and jerky for me and

crashes randomly ! You can guess I am not a fan.

So I would modify your two options to SMP and Netweaver Gateway.

Yes exactly Midhun. Correct solution depends on such factors & that is why now SAP is

providing the range of solutions & approaches to develop. However it completely depends

on our requirement which solution to choose.

But here i'd like to add that from 3.0 SAP is most likely to change lot of things. As far as i

know SAP is looking for much tighter integration with Netweaver Gateway & also they will be

providing the Offline Capabilities through the ODATA channel as well.

So it will help us to propose/choose the right approach more easily.

Integrated SAP Netweaver Gateway & SMP can always provide GREAT solutions. And after

SMP3.0 this integration along with ODATA will provide the much more benefits as Offline

capability is expected to be coming in that which is a miss in current scenario.

But David, here again we are gonna face the "How can I help you" scenario when the

customers are not interested in buying SMP licenses & wants the mobile solutions directly

based on Netweaver Gateway beacuse i Gateway licenses comes handy with their current

licensing landscape & used to be available with them already.

Very Informative...Many Thanks.

Great guys!!

At the end of the day, the solution should be satisfied all customers need.

Possibly will be SMP, Netweaver, Syclo, Consumer app, Ready to deploy app etc...

The Main challenge is to get the customer satisfy with the right solution on right time.

Lot many things are there is SAP BOX .....

You should have a look into the SMP Cloud version as well. Initial investment is low. Setup

of the Cloud connector and configuration of the SMP can be done in a day. The REST

services are the same as in the on-premise version as well.

Wrote a blog about the pros of this solution here
