Getting the IDs for a Filtered Portal in FileMaker | Databuzz

THE NEW  “LIST OF” SUMMARY OPTION  is getting lots of deserved attention:

I’ve found the performance to be excellent and it can now replace the use of Custom Functions, looping scripts etc that were previously used to generate a list of IDs for a found set of records. We’ve also another great use for it – in conjunction with filtered portals it can be used to get the IDs for the currently filtered portal records. This makes it simply to filter a portal, get the list of filtered IDs which can then be used in a multi-key relationship to group those filtered records for further processing.

Check out Andrew Duncan’s post for some unique ways to use this new feature in FileMaker 13, like grabbing a list of id’s from a filtered portal.  It’s well worth the read.
