Quick way to open a PDFViewer in your UI5 App:
const pdfViewer = new PDFViewer()
pdfViewer.setSource("/sap/opu/odata/ZMY_SEVICE" + my_path + "/$value") // my_path could be something like this "/PdfSet('file_id')"
pdfViewer.setTitle("My PDFViewer Title") // title of the popup, not the viewer
pdfViewer.open()

[ABAP] Delete all rows from index
If you want to delete all lines from a certain index, e.g. 6, you can do the following:
DELETE lt_data FROM 6 TO lines( lt_data ).
As result, your table will only hold the first 5 rows.
[JavaScript] Create date object from date string dd.MM.yyyy
Using regex, you can simply reorder the parts of your date string to create a compatible ISO 8601 date string which is accepted by the new Date() constructor.
const date_string = "01.01.2022"
const oDate = new Date(date_string.replace(/(.*)\.(.*)\.(.*)/, '$3-$2-$1'))
console.log(oDate.toUTCString())
[SAPUI5] Get data of an Item of a List or Table
All options have in common that you first try to get the binding context from the list/table element via the event. Having the right context, you can either use the getProperty() function to get a specific property, or use the getObject() function to get all data.
onClick: function (oEvent) {
// Option 1
oEvent.getParameters().item.getBindingContext().getProperty("ID")
// Option 2
oEvent.getParameters().item.getBindingContext().getObject().ID
// Option 3
oEvent.getParameter("item").getBindingContext().getObject().ID
// Option 4
oEvent.getSource().getBindingContext().getObject().ID
}
Note: When using a List, it’s oEvent.getParameters().listItem instead of oEvent.getParameters().item.
Or you could also use the sPath property from the binding context and directly get the data from the model.
onClick: function (oEvent) {
// Option 5
const sPath = oEvent.getSource().getBindingContext().sPath
// 5a
this.getView().getModel().getProperty(sPath).ID
// 5b
this.getView().getModel().getProperty(sPath + "/ID")
}
