@MohanRajuM Repeating the same thing again isn't going to help. “Set page number for my catalogue” does not make sense in English; I don't understand what it's supposed to mean exactly. We don't normally talk about ‘setting’ a page number. Please explain in detail what it is you want to do. Are you talking about adding page numbers to every page in the document? Or are you talking about defining how the page number should be presented? Or something else entirely? – Janus Bahs Jacquet Aug 8 '17 at 21:33
You’ll see in the Book file shown below that the left column contains a symbol in one of the rows called Indicates the Style Source. It means that the document in that row contains the styles that govern all the documents in the Book file if you choose to synchronize the styles. Synchronizing styles using the Book feature will synchronize your paragraph styles, character styles, object styles, and color swatches.
If you’re a self-taught InDesign user, you may not have been introduced to automatic page numbering, one of the biggest time-saving features in the program. InDesign allows you to set up the page numbering feature in your Master Pages. Then, as you add or shuffle pages, InDesign updates individual page numbers accordingly. You can style the page number any way you like.
