He all,

I've tried everything I can think of without success, so I'd like to ask if anyone else has been able to do this.

I have a file of items, sorted into various categories. When viewing an item, I have a self-relationship which allows me to see all items in the same category via a portal. I want that portal to NOT include the parent item, as it is just duplication.

Possible? Any help appreciated.

Cheers,

Sean.

Actually there might be plenty ways for achieving it using scripts, but I'll propose you an only calc method.

So, what you need is:

An unique serial number (use text format for ex ID0001, it will be clearer later why using literal prefix), name it ID

The self relationship you already have.

An value list "relIDS" based on this self rel and using values from field ID (from self relationship)

An calc field ( don't have to be stored) name it meExcluded

Substitute(ValueListItems(Status(CurrentFileName), "relIDS"), ID, "")

(now you can see why prefix in ID)

And finally, the relationship that you'll use at place of the self relationship

selfWithoutMe::meExcluded-->ID.

I can mail you the file if you need it

Djukic,

Thank you so much. I'm ashamed now to call myself a developer, given the time I spent on this.

I thought I was on the right track with the Value list items, but couldn't quite get it.

Your idea works perfectly, and you are right I wanted to avoid using scripts, as this is primarily a web based solution. Apart from the lack of elegance...

I only have one question. Have you specified the ID prefix because its necessary? I cant see how it is. Providing the ID field is unique all should be fine. I always specify an identifier for my serial numbers in every file anyway so that I can distinguish them easily, but only because its good practice, not because its essential.

Thanks again for your help, much appreciated, and I owe you a drink.

Sean.

It's because of Substitute function that could make some mess like substituting every occurrence of some digit, hence put some literal befor the number and you'll avoid major problems.
