I have my odata feed working correctly, however I am running into issues when trying to filter on a child property. The way the API is setup it expects that you run a lambda expression against the endpoint to filter on child properties. I've requested help from support but keep getting answers which don't apply or that are vague.
My URL looks like this:
Basically select top 20 from POHeaders where any POLine.ItemNumber = 55286749
Someone has to have ran into this before...is there a solution or did we buy a $1400 product that won't address our needs??
