Other than putting a portal to different related tables and such, you can't do what you want to do here.
Some solutions simulate this effect by creating layouts with buttons that look like tabs, but when you click to change tabs, you are really changing layouts.
you can show related data in a tab panel, but only related fields (in portal or not) and global fields can be displayed on a layout based on another table.
What are you trying to do?
basically I just saved a similar tabbed layout, with a different table and ran a script from the original tab to display what I wanted. Then I captured the return to go back to the original tab. It works okay. In that workaround way.
Thanks for your responses.
thats not just a workaround - it's the way to achive that when portals won't fit the needs (-:
You can create a layout template with buttons / button bars that looks like tab's. If every layout for this scenario looks the same, it feels like having tab's
Since a layout is bound to ONE table, one can have portals to display 'foreign' (related) records - OR individual fields from a related table (no portal)... so, if You don't need to have several records from the foreign (related) table, You can place those fields in an other tab
