Opportunity
Modernise and simplify with S/4HANA
Over the past few years, SiL have being carrying out a digital transformation project moving from older manual business processes to S/4HANA. Their plan in 2024 was to implement SAP standard purchasing processes.
The goal of the project was to introduce simple, modern, user-friendly applications for the creation of suppliers and purchase requisitions. The business first adopted the standard SAP applications; however, they found they did not meet their internal process specifications. Inconsistency with in-screen messaging and a lack of variable approval steps meant that standard applications could not be used within the organisation. SiL went searching for an alternative solution that would enable them to meet their initial project goals. They found that solution in Stelo.
Solution
Stelo : Customising Fiori to empower business users
In 2024-25, Arch was asked to rebuild the supplier and purchase requisition processes using Stelo. Stelo is our SAP Fiori process platform which accelerates the development of custom Fiori forms and apps, enabling the delivery of better custom apps. Arch delivered three Stelo apps: New Supplier, Create Purchase Requisition, and Create Substitute, as well as customized Stelo inboxes and dashboards to keep track of notifications and the audit trail.
The design and process flow of these applications were developed to perfectly fit the customized purchasing process SiL desired. Unnecessary fields were removed, error messages were simplified, and the screen flow followed a logical progression that their users could understand straight away. The New Supplier app empowered business users to create their own suppliers, with one step approval. Create Purchase Requisition was designed with variable levels of approval to fit the complex business needs of SiL’s hierarchy. The Create Substitute application enabled users to pick substitutes for managers to act in their absence, without disrupting the process flow. All the apps worked perfectly together for a truly custom purchasing process.
“Stelo has really simplified the process. It’s easy to use the applications because you have only what you need”
