Experts,
I'm customizing the Fiori App "Approve PO". I'm facing a problem wherein I'm not able to place any custom button on the footer bar. I'm doing the change as per a guide that describes the structure of Fiori apps. I'm doing the change in the "MasterFooterBar" view but for some reason no change of mine is getting reflected in the app.
Can any of you mention the exact file and location I need to edit to get my change in the footer bar for the Approve PO application?
