Relationship icon slow to show up

[UpNorth]

I have a question on performance. I also ran into the issue of a 2nd relationships field not appearing in a portal. Here is what I have...

Table 1(contains icon)

Table 2(Contains data the dictates the relationship)

Table 3(Has the portal)

Why does it sometime take five to ten minutes to update this field in a portal?

In table 2 I have this field:

GetNthRecord(table1totable2|Name::Icon_Attachement;1 )

Let me know if this does not make sense?

Thank you very much for your time!

Not sure about the performance issue, however the secondary related portal data I came across myself recently.

Technically it should work, but it doesn't. The answer is to have a calculation (unstored) in Table2:

Image = RelatedData::Image
