self-join relationship see's itself

I have a file showing work lists per part with a self joining relationship that shows all open work lists for the same part. It works great, but the portal shows also the record itself.

Is there a way to show only the related records buy not the one we are in?

Not without some extremely complicated calculations. It is possible though.

Basically you need to match on all records except for the current record. I do not know that I can easily find the calculation, but the theory is something like this: You need to capture the IDs for all records in the set and then using a text function (such as Substitute) you need to have another calculated field which replaces the ID of the current record with "". Then this calculated field is used as a multikey to match to the IDs and display the portal.

Sure you can, provided ValueListItems() doesn't exceed 64K, using this 'Remove Rows' technique.
