Hello BigLouie, I am a fan of yours!  Thank you for your years of hard work in the knowledgebase/sage community!  You are much appreciated!

In an effort to be obscure company code as well as  user id and password i supplemented some "personal" codes sort of speak .  But to answer your question otherwise, Yes, i have gone into the sales order manually.

Do you get any errors if you try to use the username/password in your code to launch sales order entry in the new version?

My thoughts exactly.  I suspect that R/A module has not been setup although it is active hence the error message.

No, i don't have any issues with username/password. 

Allow External Access (checkbox in Company Maintenance)?

I am not sure what the R/A module is.  I am very familiar with the Sage we have had in the past and the R/A module isn't ringing any bells.  This does give me a lead to work with, but i would like to have a little more information into what exactly it is.

Is it the Return Merchandise Authorization Module?  

ABC demo data has RMA active.
