XMlPort Sales Header Import / UPS Writeback

Hello,

I am new to nav 2013 and have be trying to import the package tracking number into the sales header (Order Only)based on an tab file. I have created the XMLPort object a tab file:

TAB FILE
S1018609 1Z723E460376110662
S1018775 1Z723E460376607475

XMLPORT OBJECT

Node Name Node Type Source Type Data Source
ShipInfo Element Text <ShipInfo>
SalesHeaderRecord Element Table <Sales Header>(Sales Header)
SalesOrderNumber Element Field Sales Header::No.
TrackingNumber Element Field Sales Header::Package Tracking No.

I have read the walkthroughs and set all the field properties correctly. When I run from the object designer and select the text file the import runs fine. When I check the sales header table for the order numbers it imported a new record as a quote instead of updating the Order.

My plan is to get this working manually then assign the XMLPORT Object to a trigger to check a shared directory and update sales orders a couple times a day. I have set up UPS to pull the data from an SQL view I created (since the backend tables had spaces in the names). That part works well.

I have was also able export / append the UPS tracking data to a TAB file during processing. I am hoping I am heading in the write direction. I have read about using access and linked tables but that seems like a work-around and those posts are 6 - 10 years old.

I appreciate any help as I am now running out of resources. Thanks in advance!!!
Erich
