count dduplicate records in a portal

[overrider]

Hello all,

i have a Portal which displays a set of Items. On the Portal i like to have one Field which displays the Number of Times the Item is on the Portal. It is no Problem that there are same Items on one Portal, i just need to know about it. So i made a Item_ID to Item_ID Relationship, a Calculation Field which does SUM (relation::constant1) . This Field only displays how many times the Item is in the Database though. How do i have to setup my Relationship please?

Thanks,

Create a relationship matching the Item_ID and parent key field to themselves, then a calculation of Count(rel::serial).

i tried the way you suggested, but it just shows how many times that item is inside the whole database, but not hwo many times it is just on the portal. i could attach a file, but i cant find the attach file button in this new forum yet...
