# Minimum requirements

{% hint style="info" %}
Deployment may be possible on previous versions of **SAP NetWeaver**, **SAP EWM**, **Android**, and **iOS**. Additional efforts may be required and some features may not be available. If you’d like to know more, please contact us.
{% endhint %}

## Software requirements

### Backend

* EWM 9.5 required

### Frontend

#### Minimum required version

PreBilt requires a minimum SAPUI5 version of 1.84.0 due to dependencies on:

* Enhanced mobile controls
* Responsive table features
* Modern theme support

#### Recommended Versions

* Development: Latest stable version from CDN
* Production: LTS (Long Term Support) versions
  * 1.84.x (Check maintenance status)
  * 1.96.x (LTS)
  * 1.108.x (LTS)
  * 1.120.x (Latest LTS)

Further information can be found [here](/prebilt-ewm/installation/ui-deployment/supported-ui5-versions.md).

### Mobile device <a href="#mobile-device" id="mobile-device"></a>

* Android 7.1 (API 25) or later
* iOS 13 or later

### Desktop

* Windows 8 or later

### Plugins <a href="#voice" id="voice"></a>

* If you are using any additional tools then additional plugins might need to be included.
* In order to develop on IOS, you would need to provide the development licence and certificates and The Config Team will adopt those in order to deploy PreBilt. (This process is excluded from this guide.)

### Required notes

* For v4.13 - [3314865](https://me.sap.com/notes/3314865) - Parameter extension of BADI `/SCWM/EX_RF_FLOW_POST` with `SY-SUBRC`
  * This note is essential for ensuring compatibility with the updated BAdI structure used in the PreBilt codebase. Later releases than v4.13 have already patched the issue so it might not be needed based on your EWM release.
  * The note addresses changes introduced by SAP to the **POST PROCESSING BAdI** `/SCWM/EX_RF_FLOW_POST`, which directly affect PreBilt’s implementation. Specifically, it resolves issues related to the handling of the `SY-SUBRC` return code during RF flow post-processing

### Recommended notes

* For v4.13 onwards - [3515438](https://me.sap.com/notes/3515438) - /UI2/CL\_JSON corrections - PL20
  * This note is recommended to ensure correct JSON parsing for PreBilt Frontend communications.

## Network configuration

For EWM, HTTPS required.

There must be a signed by registered certificate authority in each SAP system connected to. There must also be a direct connection from device to SAP and the domain is resolvable by the device.
