CAP

[CAP] Download MTA deployment logs after deployment

 , , , , , , ,

With this simple command, you can download the MTA deployment logs of your recent deployment. Instead of manually having to use cf dmol -i <operation id>, just save the command (replace appId with your Id) as a shell script, make it executable (chmod +x) and run the script after your deployment. It stores the recent logs into the folder logs.

dmol is short for download-mta-op-logs

cf download-mta-op-logs --mta <appId> --last 1 -d logs

To just have a quick look at the recent logs, use

cf logs <appId>-srv --recent
CAP

[CAP] Check if User exists in SuccessFactors

 , , , , , , , , , ,

To check if a record exists, you can simply use the HEAD query.

“HEAD is almost identical to GET, but without the response body.” (https://www.w3schools.com/tags/ref_httpmethods.asp)

Unfortunately, there is no shortcut in CAP for a HEAD query, so simply use send with method HEAD.

    sfsfSrv = await cds.connect.to('sfsf')

    try {
        await sfsfSrv.send('HEAD', `/User('${userId}')`)
        return true  // status 200
    } catch (err) {
        return false // status 404
    }

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()
