So I have been given a project that need to work with GP.   I need to
be able to submit Payables Transaction Entries from a web page.  I am
making some basic assumptions and trying to find the correct schema and
process to provide this functionality.  I hope someone here can
validate my assumptions or point me in the right direction
Assumption 1 -  I need a valid VendorID In order to submit a Transaction Entry. 
This
means that I need to retrieve a list of valid VendorIDs from GP, and
allow the user to select a Vendor.  I then would need to retrieve the
default information about that Vendor (Address, Currency, etc) to
populate my Transaction Entry with valid values.  
How do I use eConnect to provide a list of Vendors and Vendor information.  
Thanks
