Transactions brought in through eConnect will have MDA information created according to the setup in the Account Analysis Defaults window. The MDA information created by eConnect will be the same as what would be defaulted when manually entering the same transaction in Great Plains. However, for MDA Groups in which Quantities are tracked, Quantities information is not defaulted. These records can be updated at a later time by calling the taMdaUpdate node. This node allows you to update the Quantities and Posting Description fields only for those records in which Quantities are being tracked.
