I tried to take a look at your file. Unfortunately I was not able to understand the labels on the buttons so didn't know which to push to present your problem.
If you could re-lable the key buttons in english, I would be happy to take a look.
I had a check, found a few things:
- the portal on the pop-over is filtered, I disabled the filter, but no cure
- there is only one row in the portal, the one that lets you add a new row. Except that the X relation does not allow the creation of new records. Mystifying.
- I also removed the sort on the portal, I don't get why the sort would change anything, but even without it, there are no products
- I deleted the fields from the portal, and inserted them back: now I get the place holder displayed
I tested your database in FMPA 16, I guess your are using another version. I can't explain what's wrong, unfortunately.
use the drop-down list an go to Form Layout > Invoice_form.
I really don't understand why I can't see my products everything is okay
The issue with the file may have been corruption. The first time I opened it, FileMaker created a recover log.
Attached are the recovery log and a slightly modified version of the file.
I added a few base table layouts so I could see if all of the IDs are correct and re-created the Import_Products portal. Initially the new portal showed the product records and the original portal did not. I duplicated some of the fields from the original portal in the new portal and then both portals showed the records.
In the Invoice layout, the original portal is at the bottom of the layout and the new one is where the original was.
At the moment this file is working, but due to the corruption in the file, I would recommend starting over with a new files.
