While importing from WeSuite to SedonaOffice if you encounter an error that items/parts cannot be imported, or if the import goes through without error, but then the items/parts do not appear on the resulting job, this means those items/parts have not been properly mapped in WeSuite.
All mapping is done from within WeSuite and can be found in WeSuite under Pro - Tools - Program Options - Accounting Interface Nappings – Items (or Parts). The right side is the accounting side, which shows the items/parts available for mapping from SedonaOffice. If an item has a map icon, it means it has been mapped already.
After confirming the items/parts in question have been mapped you can remove and re-add those items/parts to the WeSuite quote and then attempt to import again. Removing and re-adding the items/parts is important to confirm they are the actual items/parts displayed, and not different items/parts that have been typed over (something WeSuite allows you to do).
