What is Offline Mobile App Development

The development of offline mobile applications meets a critical demand for SAP users. In our daily lives, we have all come to rely on internet connectivity. Similar to consumers, businesses depend on mobile or local coverage to run their operations and obtain real-time insight into them. Specific business processes and industries are compelled to function offline using ineffective non-digital solutions if they operate in a situation with patchy connectivity. Even in the most remote areas, supply chain deliveries need to be traced, and forklift operators require the most recent instructions from the remote warehouse to the loading dock door. Oil rig workers also need to complete their job duties and report them. For each of these use situations, the enterprise resource planning (ERP) system must automatically synchronize crucial company data without loss while business apps are fully operational when offline.

Your organization depends more on your systems, applications, and customized features to communicate, access data, and maintain automated operations as you go forward with your digital transformation. Maximizing uptime occasionally depends on your team's capacity to work offline because productivity is so directly correlated with tech accessibility. However, it's easier said than done to create and manage offline mobile apps. Most modern developers are accustomed to working online and have created a vast number of web applications. They do not comprehend the complexities and subtleties involved in creating enterprise-grade offline mobile apps as a result. 

Enterprise offline apps differ for a variety of reasons, including:

• Connection Availability

Being completely connected or completely offline is a hurdle that is very simple to overcome. When a user's connectivity is erratic or inconsistent, problems occur. As an illustration, a user might have poor bandwidth for 30 seconds, drop connectivity for a few minutes, and then experience low connectivity again for 30 seconds. How can you safely send tonnes of data to SAP in that short of time?

• Softer Standards

On mobile networks, remote areas typically have low network bandwidth and high network latency. So that they may discover the greatest connections, phones will swap between wireless and network providers. Mobile applications must comprehend the network switch and avoid losing data packets.

• Cost of mobile data plans

Data can be quite expensive in some places; therefore, people are careful not to use too much bandwidth when sending data over mobile networks. When customers utilize their own devices that use their data bandwidth, things get more difficult. Apps must therefore plan data delivery at the appropriate moment utilizing the appropriate wireless networks.

• End-to-end protection

Any offline app must have enterprise-grade security for all phases of data processing, including posting to SAP, data in motion, and data at rest inside the device.

• Managing conflicts and errors

To ensure the integrity of data in SAP and avoid overwriting data that may have already been submitted by other users, you must handle conflicts when publishing the data back to SAP when there are hundreds of users working on the same SAP transactions offline.

• The back-end’s scalability

Make sure SAP is not overloaded with data overload coming in from all the apps because there may be 100s or 1000s of users who might all post data into SAP at the same time when they are back online (for example, returning to the office at the end of the day).

• Support for devices

There are a huge variety of devices on the market, including tough devices from companies like Zebra, Honeywell, and more. Because of this, your offline apps must function reliably on a variety of devices and mobile networks using different mobile operating systems.

These difficulties and others make creating and maintaining offline apps very challenging, time-consuming, and expensive. Fortunately, technology has matured to the point where rapid application development (RAD) platforms enable your development team to build and deploy customized offline apps more quickly and easily, allowing you to expand your SAP system to accommodate your particular operational needs.

In general, they are all speaking the truth when they say that their RAD platform gives you the ability to develop offline mobile applications, however the level of offline development that RAD platforms enable might differ greatly. Users can enter or capture data offline on the majority of RAD platforms that are interoperable with SAP and the other top ERP solutions. When network service resumes or your field workers return from a remote area where they lack internet connectivity, they also sync with your SAP system. The apps' approaches to managing conflict and errors, preserving data consistency when devices move networks, and, most importantly, the capability to create SAP documents in an offline mode while replicating SAP business rules are where they diverge.

To support either lightweight or heavyweight offline apps, RAD architects must categorize their offline use cases.

• Portable Offline Capabilities

Some platform architectures simply solve the issue of brief, sporadic outages or periods without a network connection. They could be read-only offline apps that function with forms or data gathering. Your developers might be able to make mobile apps that function offline using these platforms. However, the user experience those apps provide is distinct from that of doing work online. Only offline data can be collected or entered by employees, and when a network connection is restored, the app retains that data and syncs it with SAP.

If your staff uses the mobile app for a short period, such as when utility service is briefly interrupted, they usually won't notice much of a difference. However, UX suffers if the outage continues or if the employee frequently uses the app on a mobile device while out in the field. Your staff will need to make adjustments to their regular work processes and shift to thinking "offline mode," keeping track of what they're doing and, regrettably, what they might need to go back and repair later. In turn, this lowers the information's accuracy, results in haphazard integrations, and raises audit and security concerns.

• Powerful Offline Abilities

Fortunately, alternative RAD platforms make it possible to construct offline mobile apps that are appropriate for the challenging, complicated real-world circumstances that SAP users encounter. The apps created for these platforms carry out complete SAP transactions in offline mode with all applicable SAP rules, data synchronization, and error handling. They also give your employees the same experiences whether they spend a short period working online or offline or a whole shift.

For SAP users, a proper offline-first strategy for mobile app development is essential. When using the app, Offline-first believes that users will either be completely offline or just have sporadic network connectivity. Users can perform SAP transactions on mobile apps created by developers using platforms that allow offline-first apps in the same way they would if they were connected the system. For instance, without writing any code, users can design SAP documents that can run whole SAP transactions even while completely offline. Use cases include carrying out delivery shipments or performing equipment maintenance in the field. For more information on SAP warehouse management, see Scanning During Receiving in the Warehouse.

Then, users can run SAP documents to manage their time, find and order components, register equipment use, and more. Without altering their processes or being concerned that crucial information is slipping through the cracks, employees can continue working at their regular speed. Heavy-duty offline software use cases will cover light-duty use cases, but not the other way around. Even if your firm only has a small number of heavyweight offline use cases, it would still be desirable to choose a RAD platform that supports them because it would automatically take care of your enterprise's lightweight use cases.

End Note…

How much value your mobile applications give offline depends on you when you select a low-code development platform exclusive to SAP and equipped with market-leading capabilities. It is recommended to start by examining the business processes and workflows of the employees who will use the app and specifying the information they must gather and share with SAP modules. Prioritize characteristics next, separating those that must have from those that are good to have but not essential. Remember that employees who work away from a PC or near a machine's user interface may have distinct needs.

If employees must gather or use photographs, databases, or videos, you will also need to decide on the best approach to save data utilizing local storage on the device. Using Pillar, you can effectively design, develop, and launch an app that will improve productivity and efficiency across your entire company. Since they always have access to the tools and data they need to complete their jobs, there is little that can stop employees from utilizing these devices to prevent them from doing their work. Additionally, they won't need to alter their workflow or worry that when the app syncs with SAP, they'll have to rely on their memories or notes to fill in the blanks using an SAP-specific platform.

If you have decided upon developing an offline mobile app, then you must take assistance from someone that knows of this and also the ones that are experienced. Such as, you can take the help of an organization that is well-known and also have experience.
