I didnt get what i am looking for, can you please tell a scenario where can i use this savable data page . Tell me with an example like what should be present on a section inside a flow action and how to call this savable data page in section and later in flow action post processing to save it. Please share screen shots. I am really struggling to learn this . There is no proper details on this in PDN.
Go through the new CSSA course (Pega 8) on Pega Academy, especially the lesson "How to read and write data to a database" under the chapter "Information Exchange: Database Updates". This should explain the purpose and working of savable data pages.
