I want to put a button on my Purchase order form to create a duplicate record. My form is related to another file for line items, which I input through a portal. The problem is when I duplicate a record none of the portal items show up. Is it possible for FM to duplicate the contents of a portal too, or do I have to avoid using the portals?

You need to duplicate both the master record and the related line items records ...

Perfectly doable, a bit convolute ... the script would look like:

Set field (gID, OrderID)

//Note: this is the "original" OrderID, OrderID is a unique serial number,gID is a global field

Duplicate master record

Go to related record (Show, Relationship to line items linking gID::OrderID)

//This selects the line items belonging to the "original" OrderID

Set field (gID, OrderID)

//Note: this is the "duplicate" OrderID

Perform external script in Line Items, see below

Go to record [Last]

Loop

Duplicate record

Set field (OrderID, Relationship to Orders::gID)

//This steps puts the "duplicate" OrderID in the duplicate line item record

Omit Record

Omit Record

Exit Loop If (Status Current Found Count < 1)

End Loop

Hey thanks for the help. A little daunting seeing as I've never actually done a script, but I tried it out. I think I got it except I got hung up on one action:

Exit Loop If (Status Current Found Count < 1)

FM would not allow me to type it this way "not recognized as a flag" or something like that. Maybe I should read a book.

Sorry, the sintax was approximate ....

the correct one is:

Status (CurrentFoundCount)<1

Thanks again. It almost worked this time. It copied everything 3 times. I guess I'm having a problem with relationships (with my database that is). Right now I have a relationship between PO.fp5 (the master file) and line items.fp5 (related file) with the two joined on a field called PO Number (Auto-serial). Do I have to create some more relationships to the new global field created in PO.fp5?

You've just to make a new relationship between the global field and the PONumber in LineItems ... check the script in LineItems and see if you're omitting both the original record and its duplicate ...
