SQL to XML to Spry Table not working

Question

I have created a table that uses PHP to pull mySQL data... it
works fine.
But if I copy the SQL statement into another php file, then
use the "Export to XML" function in order to use that XML file as a
Spry dataset, so that I can sort my columns, I receive an error
while creating the dataset.
The problem is in the WHERE statement in the SQL. The code is
attached... But here it is as well
WHERE subtbltripparticipants.tripid = '$_GET[trip_id]'
It's the $_GET that is freaking it out. This code is supposed
to pull the variable from the URL. It works in a regular recordset
in DW, but not in a recordset that is exported to XML. Is there a
different syntax to use? How can I get the variable that is sent
via URL to be used in the Spry dataset as a filter?
When I created the dataset, and choose the php file with the
SQL in it as the "XML Source", I get "Expected comment or
processing instruction(2,1) in the "Row Element" section, where the
nodes should show up. I don't understand this error and don't
understand why the SQL works in a standard table, but not in an XML
export for Spry.
Please advise. Thanks,
Bubba

Answer 1

Ok,
I tried that and it basically bring you to OLI7BW as suggested above.
1. At this point, how do you know which of these it is actually filling:
2LIS_11_VAHDR Sales Document Header Data
2LIS_11_VAITM Sales Document Item Data
2LIS_11_VAKON Sales Document Condition
2LIS_11_VASCL Sales Document Schedule Line
2LIS_11_VASTH Sales Document Header Status
2LIS_11_VASTI Sales Document Item Status
2LIS_11_V_ITM Sales-Shipping Allocation Item Data
2LIS_11_V_SCL Sales-Shipping Allocation Schedule Line
2LIS_11_V_SSL Sales Document Order Delivery
2. Also, what does it mean when after running OLI7BW wide, with no restriction on my system, still rsa3 shows no records for 2LIS_11_V_SCL?
Any other way to confirm that there may not be any data in 2LIS_11_V_SCL?
Or any way, to make an entry which reflect in 2LIS_11_V_SCL so that I can verify if OLI7BW actually fills the setup table?
Thanks
