Sub-summaries in a Portal?

[tDot]

Does the concept of sub-summaries exist for portals?

I have an invoicing solution that has files called INVOICE and LINE_ITEM. I have a portal on my Invoice Layout that shows line items like this:

Category 1 1000.00

Category 1 2000.00

Category 2 1500.00

Category 2 3700.00

I want the Line_Item portal on my Invoice form to *subcategorize* the info (like I could by using subsummaries in the LINE_ITEM file to print a report that shows:

Category 1

1000.00

2000.00

=======

3000.00

Category 2

1500.00

3700.00

=======

5200.00

Can this be done in FileMaker 5.5?:??

Yes it can be done, but would require a lot of settings, in the Line Items file as well as in the portal side.

Is it worth the efforts ? Why don't you want to rely on sub-summaries that would be quite more handy to do the job ?
