In this part of the blog, you will see how you can integrate your SAPUI5 application as Task UI in workflow.
Before we start the learning, there are few things you must know about the user task of SAP Cloud Platform Workflow.
The task associated with user-task activity in the workflow are available under the Tasks list in My Inbox application. The user interface configured for the user task is rendered as task UI when an end user opens the task in My Inbox. Application developer is, thus, given the flexibility to integrate any custom UI with the user task of workflow
This means that your existing custom application needs to be modified so that it can (a) access the task-data, (b) bind the task data with the UI elements of the application and © implement code for the task actions like complete, cancel etc.
Let us now learn how can you do that.
