A common error message that pops up when importing to Dynamics GP states: Node TransactionInsert not found in TransactionType. The element node is required for this transaction type.
This error normally occurs if the map is grouped incorrectly compared to the key fields selected for the data source. Incorrect grouping on the header node can cause the header to be sent to eConnect multiple times.
To determine if this is the case for you, send the map to Microsoft Dynamics GP – File and check the XML output file.
This error can be resolved by adjusting the key fields/grouping on the node usually by making them the same.
