finding records in one layout based on a found set in another layout from a related table
I'm sure this has been answered before in the forums, but I have not found the answer although i'm not sure i wasn't searching for the right phrase or terminology.
I have filemaker pro 11 on one mac and filemaker pro 11 advanced on another.
I have multiple tables and relationships in my database but the two concerned here are Invoices and LogBook. In the logbook table I have a field called "related inv id". In the Invoice table I have an Invoice Id field that is automatically populated in sequence with each new record. I have these two tables joined with the mentioned fields. Just the plain old regular join that you get when on the relationship diagram, you drag one field from one table occurrence to a field on another table or occurrence.
One invoice may have multiple related logbook records or just one, or it may have none.
One logbook record may only have one related invoice or it may have no related invoices but it can not have more than one related invoice.
What I would like to do:
I would like to search the logbook records for certain criteria and then find invoices not related to that found set.
What is the easiest way to do this? And what are the pro / cons of each way?
I have worked with portals but I don't think this is what I want to do, or at least i'm not sure how to make it work right. I have also made a few simple scripts (for other things not related), so I'm willing to try either of those, but I still feel like a beginner with filemaker so be easy, lol.
