Run an xmlport passing parameters

Alisha

I need to do a simple import of Items/Quantities for a Sales Order. On Classic I would create a dataport, pass the doc. no. using a function, and then run a simple dataport based on integer with the fields I want, and then create the lines by code.

I've tried doing the same using an xmlport, but I cannot run it from a page, I get the error that asks for a COMMIT.

Is there a simple way of doing this on RTC?

The file won't contain the Sales Order No., and I can't see the way of sending it to the xmlport ...

Thanks!!
