Frequently asked questions
PreBilt Overview
Does PreBilt replace the SAP EWM framework?
No, PreBilt for SAP Extended Warehouse Management (EWM) sits on top of the existing EWM RFUI framework to enhance its capabilities with an intuitive mobile barcode scanning experience.
Is PreBilt an alternative to SAP Fiori for EWM?
SAP Fiori is designed to be used to complete simple SAP tasks on a desktop such as work approvals and reports, it has not been developed as a mobile solution for barcode scanning. Fiori has limited applications for use with SAP EWM and is unable to convert any custom transactions. PreBilt for EWM is specifically designed to complete EWM transactions on a mobile device and offers UI and functionality benefits over Fiori.
Is PreBilt an alternative to SAP Personas?
SAP Personas is purely a UI solution for personalising SAP screens, allowing screen designs to be altered to make them more user friendly. It is designed for use with simple SAP transactions that are executed on desktops. Its use for RFUI is only supported from SAP S/4HANA 2021 and in limited use cases for EWM processes. Significant development work is required to customise screens across a range of transactions. PreBilt for EWM is specifically designed for mobile barcode scanning, completing EWM transactions on a mobile device and offers UI and functionality benefits over SAP Personas.
How are roles/rights propagated to the PreBilt frontend?
PreBilt leverages the underlying SAP system for user authentication and authorisation. The user ID, along with associated roles and rights, is sourced directly from SAP, eliminating the need for separate maintenance or configuration within PreBilt. As PreBilt uses the standard SAP user credentials, no additional SAP licence fees (such as digital access) are required. Single Sign-On (SSO) is supported for streamlined access. Furthermore, PreBilt operates on SAP’s standard RF execution infrastructure (RFUI), ensuring that standard SAP roles are automatically applied.
How do we maintain S/4HANA Clean Core Strategy?
No SAP APIs are required. PreBilt uses the SAP RF infrastructure best practice of creating a custom display profile. PreBilt core logic is added to the two template screens while complying with clean core best practices.
How are push notifications implemented/ is a new service required?
SAP standard BAPIs are used for the push notifications functionality; no additional services required.
What about the use of standard services for IAM (BTP Cloud Identity Services)?
We have worked closely with SAP's Product Management team to ensure that PreBilt is fully aligned with and supports the EWM Roadmap. Our recommended approach is to host the UI inside EWM and avoid utilizing BTP. This simplifies infrastructure, improves performance, and reduces additional complexity. Authentication: PreBilt doesn’t use IAM but effectively relies on standard SAP login and supports SSO (Single sign on), if required.
Can you provide a list of example transactions currently supported, along with real-world deployment examples across IM, WM, EWM, SRM, PP, and QM?
All standard RF transactions are included plus the ability to support custom transactions if they are built using RF best practices which can be found here.
Functional Capabilities
It is not always efficient for operators to follow the picking route suggested by SAP EWM. Is there a way for PreBilt to change this?
We have added specific functionality that enables users to view all the picking tasks and swipe through the screens so they can start on the task of their choice, enabling user-based decisions to optimise SAP Extended Warehouse Management (EWM) and increase productivity.
Can PreBilt help with employee engagement?
PreBilt for EWM offers gamification for SAP EWM, which sees game mechanics added to warehouse tasks. Users can compete against each other in competitions or challenge themselves with ongoing personal development targets, which they can beat to advance to new levels, win trophies and claim rewards. The results are improved employee productivity, motivation and engagement.
Does the solution include document capture functionality? For example, can users take photos of certificates and automatically attach them to Goods Receipts?
PreBilt EWM provides image capture functionality, which takes advantage of the SAP image repository or external web link where images are stored. PreBilt can be configured to attach images to a goods receipt or for additional use cases. More detail can be found here.
Can the system use AI/ML to extract information from captured documents and populate data fields automatically?
PreBilt offering does not currently include integrated AI/ ML from capture documents as part of the standard software offering. We have previously integrated OCR software within the PreBilt applications custom to customer requirements.
What do the standard PreBilt RF screens provide out of the box?
More information can be found here.
Is there a best-practice, standard configuration template available for initial setup?
Yes. We offer a BC set that serves as a template for standard configuration.
How are screen customisations handled? Are they role based, persona based, or individually configured?
Individually configured.
Can PreBilt be used to monitor warehouse performance?
PreBilt can deliver live SAP data as key metrics to help enhance and accelerate decision making. Key metrics can be displayed on transaction screens to provide information that aids and informs the process or task. Key metrics can also be provided as an overview on one screen to allow a holistic view of the current supply chain operation, with all metrics tailored to specific customer needs.
In PreBilt EWM, how do you control what happens when a user presses F7/Back when exiting a warehouse order?
PreBilt does not change SAP functions that are already customisable. If you want to remove the Back button, you must do this in SAP standard by editing the Function Code Profile. PreBilt can only enhance what SAP does not expose. You can use PreBilt Message Overrides to pre answer hard coded SAP prompts, such as overriding the “Carry Goods to Destination” prompt to always answer ‘YES’.
Technical & Hardware Considerations
We operate on SAP RISE, what issues/additional activities may be included as part of a PreBilt Installation?
PreBilt complies with all required prerequisites for raising an add-on installation request to SAP RISE Private Edition. It is SAP certified, delivered as a TR with comprehensive documentation. No middleware is required, the UI5 sources are maintained as a BSP app in SAP. PreBilt is all SAP centric, so no issues are expected.
Does the solution work on all mobile devices (iOS, Android, rugged devices, etc.)? If so, why is SAP Fiori not leveraged as the default UX layer?
Yes, on all Android (OS8 and above) and Apple devices. PreBilt can also be used via your desktop or mobile browser.
Can users download tasks to their device, work offline, and then sync and upload the results when back online?
The recommended approach is to use online. But we also understand that there are specific environments that may require specific use cases for downloading/storing/processing back to SAP, which the PreBilt solution can cater for but requires customisation.
Where are documents stored once captured or uploaded? (e.g., SAP DMS, cloud storage, ECM, etc.
Dependent on customer. Typically, customers hold images in a SAP Image Repository, however, PreBilt is designed to operate flexibly with other storages/ repositories.
PreBilt Licencing, Support & Costing Model
Can you provide clarification on the costing model, including licensing, hosting, and support components?
Costing model – Software subscription Licensing - More information can be found here. Hosting – More information can be found here. Support components – Under your licensing agreement we provide support via our support helpdesk as per agreed Service Level Agreement (SLA). We also offer 24/7 P1/ P2 PreBilt support which can be arranged via our commercial team.
How are licences provided and renewed?
Upon project commencement TCT provide a temporary license key that is loaded in the clients SAP system to allow activities to commence. Once commercial arrangements are complete for licenses, TCT provide a full license key for agreed users & length to the customer to implement in their system.
Once the license key is 1 month away from expiration, TCT will begin arranging a renewal with the client and provide a new updated key for the customer to install.
Training & Enablement
What end user training materials are available, and how can they be tailored to client requirements? For example, can WalkMe style guided learning be integrated.
Our primary source for end‑user training is the Documentation Portal - Particularly the Using PreBilt section.
We can also offer remote/ on-site super user training sessions (typically a 2-hour session)
