Just to get more information. Which PPM version are you using?
Starting from PPM 9.20, PPM does not have view all for table component.
At least staring from 9.12, PPM can remember page count for every table component field for every request type. I am not sure whether it can remember "view all", but if you change page count to a big number, PPM can remember the setting.
Like I said, we use PPM 9.32.0003 (latest release).
PPM didn't memorize the information stored in the "Show xx Each page". If you set Show 80 each page, then log of / log in / display the same request, the value will be 5 again. See attached screenshot.
This is really annoying. If the table component has more than 5 records, the user will certainly miss important information.
I've raised the issue via an Enhancement Request, but it was unsuccessful.
I've ever tried to find a customized way as a workaround to this stupid limitation, and it was unsuccessful (side effects).
