# Functionality

The app provides the following functionality:

* Enables users to access and interact with PreBilt applications and SAP data without internet connectivity.
* Download master and transactional data from SAP and stores it locally.
* Administrators can predefine synchronisation ranges via **App Master Data**, reducing user efforts.
* Provides flexibility to configure which apps should be set as default for synchronisation, aligning with business needs.
* Business or user can define specific data parameters for synchronisation, focusing only on necessary information.
* Provides metrics to show when last sync of data from SAP took place.
* Set PreBilt to work in offline mode only by setting the '**Offline Mode**' flag in the '**Settings**' tab.
* An '**Outbox'** area where user can review any offline work completed, pending '**Check-out**' synchronisation.
* Synchronise data with SAP at the push of the '**Check-Out**' button, in an intelligent and sequential manner to avoid any issues in the process - for example, if new work order has been created, worked on, and completed, PreBilt will process data in logical sequence to ensure successful processing.
* Ability to modify data created or changed in offline mode from the 'Outbox'.
* Ability to mass-delete all pending data.
* Intelligent error-handling, enabling user to identify data errors and provide SAP error response messages to help resolve them in a efficient manner.
* Configurable settings allow to define what data to be automatically deleted upon user logout (online-mode).
* Ability to clear any downloaded data from the offline database using "**Clear Data**" button.
* Establish local authentication and prevent login issues in offline mode, in the event of accidental forced closure.
* Enhanced measures in place preventing unintended offline data loss/wipe.
* Configurable sync reminders prompt technicians to sync data back to SAP, ensuring timely updates.
* Enforce Sync - set a rule that will force a user to sync data after specific period of time (in hours).
* Offline enabled
