For multiple records per page in Data Merge you must have only one set of placeholders, in the upper left position, on the template page.
If the placeholders are on the master page only the text frame holding them, and any other frames grouped with that frame, should be duplicated, but if you prefer to do the merge from a document page you can set up two master pages, one with only the merge placeholders and ohter objects you wich to duplicate, and one with information that should not be duplicated. Apply the first master to the template, then after the merge apply the second master to the merged pages.
A final Warning: DON'T use preview with multiple record merges. It is buggy and can result in incorrect merges and templates that will never work properly again.
thank you so much for your kindly reply!
It is highly appreciate that your translated from Italian and you reply to me!
I tried to use your above instruction.
I merged the data from the MASTER PAGE A and I've got the documents in multiple pages.
In total (for this test) I have 6 pages.
Now I have to MERGE the data from another DATABASE.
These data have to be added only on the top of each page.
These data are unique for each page (products category).
Hence I have created the MASTER B adding the text placeholder on the point in which I need it.
When I merge the data of the MASTER B, the operation cancel the data merged with MASTER A.
Peter, any other good suggestion from you?
Thank you so much in advance!
Data Merge is a very basic tool. It can work with only a single data source per document. You'll need to combine the data bases in some way so that data from both is in a single record.
Thank you for your help Peter!
