Hello there, wondering if someone can help, i'm trying to build a Sales Order Saved Search which only includes SOs with a specific number of related invoices (in this case either one or two invoices, we often issue multiple invoices so there is a need for this), have built on a previous saved search but struggling to find a formula that will do this, see below for snips of criteria/summary and columns, i have tried to add something into the summary to expose all those with just 1 invoice but no luck , would appreciate any advice
