SAPUI5 is a client UI technology based on JavaScript, CSS and HTML5. Web apps developed with SAPUI5 run in a browser on any device like mobile, tablet or desktop PC. When users access SAPUI5 app, a request is sent to the respective server to load the application into the browser.

SAPUI5 comes with all main SAP platforms but can also be used outside the SAP ecosystem because a large part of SAPUI5 had been open sourced with OpenUI5.

When it comes to SAPUI5 - there are dependencies between SAP user interface technology(SAP_UI), SAPUI5, AS Abap and SAP Fiori front end server (FES).

For example, SAP S/4 HANA 1909 supports below

SAP Fiori front end server - 6.0
SAP Gateway - 7.51 to 7.54
SAP UI - 7.54
SAPUI5 - 1.65

Basics Of SAPUI5 vs OpenUI5

For audience like me who are new to UI5, here is the basic difference b/w SAPUI5 & OpenUI5.

  • OpenUI5: It is open source i.e. it is free for use to build web applications. Its core is based on javascript, jQuerry and LESS.

  • SAPUI5: It is mainly used by SAP customers with certain kind of license. It is integrated with SAP std. products like SAP Hana, SAP Cloud Platform, SAP NW 7.4 7 higher and included in SAP UI technology component (SAP_UI).

Versioning of SAPUI5

SAPUI5 uses a 3-digit version identifier, for example 1.26.4. These digits have the following meaning:

  • The first digit (1) specifies the major version number.

  • The second digit (26) specifies the minor version number.

  • The third digit (4) specifies the patch version number.

The version number for each new SAPUI5 release contains a major and minor version number. The patch version number is only used to identify patches within a release.

For developers What's New In SAPUI5 1.71
One of the key enhancement is that there is visual improvement of the column separator to enhance visibility. It is applied to the SAP Quartz Light theme and both SAP Belize themes (along with the high-contrast themes) and there are no differences between the cozy mode and the compact mode.

With the release of SAPUI5 1.71, the SAPUI5 tool for Eclipse will no longer be maintained. Version 1.71 is the last SAPUI5 version for which SAP will update the SAPUI5 tools for Eclipse and going forward SAP recommend the use SAP Web IDE as the development environment for SAPUI5. There are other alternative tools which support javascript development like

Visual Studio
