SAP UI5 and OpenUI5 provide a cool numeric input control called sap.m.StepInput. For some reason it cannot be emptied though: removing it's value makes it be zero, not empty. Unfortunately, this makes it impossible to use it as a filter or for optional inputs. Here is a simple custom control, that extends sap.m.StepInput and allows empty values (resulting in empty strings).

Did you know, there is a 100%-native web service built into SAP NetWeaver, that performs any read-only OpenSQL statement provided? Build SQL-based data extractors, ETL-process, do rapid prototyping for UI5 apps - all without a single line of ABAP code! Here is how...

OData Services and other web services running on SAP NetWeaver use so-called CSRF tokens to secure requests, that can potentially modify data (i.e. POST, PUT, DELETE, etc.). Here is how to handle them in non-SAP applications.

One of the main differences between SAPUI5 and OpenUI5 is that the latter has noch charts. But is it drawback really? Here is a dead-simple way to use any JavaScript charting library in OpenUI5: no custom controls, no special API - just the visualization lib of your choice!

SAPUI5 and OpenUI5 both provide two totally different controls for data tables: they are called "grid table" (sap.ui.table.Table) and "responsive table" (sap.m.Table) in the Fiori styleguide. As the names suggest, one is responsive and better suitable for mobile apps, while the other is more desktop-oriented. But there are many more differences! The trouble is, that the effort to switch from one table to another is pretty high, so think carefully when making your choice!

The number of business web apps powered by PHP is rapidly increasing, which leads to a growing need for backend-integration with enterprise systems like ERP, CRM, WMS, etc. However, when it comes to large business software like SAP, integration is not really straight forward - especially with web applications built with totally different technology. This article aims to give an overview of different possibilities to exchange data between a PHP-based web app with a SAP backend.

SAPUI5 and OpenUI5 seem pretty self-content, but there are still lot's of cool third-party libraries, that you might want to use. Since UI5 is based on jQuery, the majority of jQuery plugins out there are perfectly compatible with it: all those tools, widgets, charting libraries, etc. Here is how you can include them in your UI5 project properly.

This tutorial shows, how to make an OpenUI5 web app work offline by using the workbox toolkit to convert it to a progressive web app (PWA).

Fiori apps make it easy to access your SAP system from connected mobile devices. But what if you are offline or the connection is unstable? In this article, I am going to introduce and compare the different approaches to making SAP UI5 work offline.
