Thanks for a quick response.
it's not depending on a type of field - Connector doesn't write data to any custom field on Sales Line, no matters if it's Decimal, Date or Code (the problem is with writing data into ERP entities, not CRM). There aren't any errors in Connector's log, all default fields are filled properly during integration. As I said - it's seems that the Connector just ignores those fields even though they are mapped in "Order to NAV Sales Order" map.
I think the cause may be a specific situation of Sales Lines - they don't have a separate Integration web service and they are operate by a part of Integration Sales Order web service. Also, it's seems to be some issue with Connector, because when I'm using this Web Service directly from SDK, it's writing data into custom fields of Sales Line without any problem.
I wonder if it isn't some general Connector's problem with this kind of "sub-entities" as Sales Lines. Or maybe should I add those custom fields to some other NAV Page than I told in a first post? But if that would been the cause, they shouldn't be visible in Connector's map, am I right?
