Product Stores & Purchase Orders

[Nathan Hampton - Circuit Rider Books]

Now that I've (finally!) managed to track down the problem, I can ask  
what to do about it!

BACKGROUND:

This problem occurs with revision 678902.  I haven't checked more  
recent versions because I'm trying to get us up and running before  
changing anything else.  If this has been fixed or changed, I  
apologize in advance for any inconvenience.

Every time I try to create a purchase order, I get the following:

After tracing the execution through the source files, I managed to  
determine that when initorderentry doesn't find a ProductStore in the  
request, it looks for one in the WebSite, and since I don't have a  
WebSite with the ID "OrderEntry", it can't find one.

QUESTIONS:

1) What is the significance of the WebSite-ProductStore association?
2) What should I consider when deciding which of my five ProductStores  
to associate with the WebSite "OrderEntry"?
3) I understand the need for a ProductStore when creating a Sales  
Order, but why do I need one when creating a Purchase Order?  If it's  
just to set a default Currency UOM, isn't there -- or shouldn't we  
find -- a better way to do this?  Alternately, why can't we just skip  
the default and set the Currency UOM on the next screen, where we  
already have a way to change it?

Thanks for the help!

There has been some work on this lately, that may cause this.
suggest you open a Jira, so the parties can check what they did.
