Tech Tuesday: SmartConnect Purchase Order Map Error

If you are running a purchase order map and receiving an error that says “370 /* Subtotal (SUBTOTAL) does not match the line item totals” we have an easy fix for you. The Microsoft eConnect SDK has this field marked as required, as it used to be required in older versions of eConnect. The SmartConnect required fields are based on the eConnect SDK, and even though the field is no longer required in newer versions of GP, Microsoft still has it marked as required in their SDK, which means it shows up as a required field in SmartConnect.  

The field will currently auto-calculate if you leave it blank, however, you cannot leave the field blank because SmartConnect believes the field is required.

The easy fix is to run the following script in SQL server management studio against the SmartConnect database.

This script is if you are on SmartConnect 2018 or lower.  

UPDATE SmartConnect..[Field] SET Required = 0 WHERE Node = ‘taPoHdr’ AND TechnicalName = ‘SUBTOTAL’

If you are on SmartConnect 21 and higher, you will need to run this script.  

UPDATE MsGpField set Required=0 where TechnicalName=’SUBTOTAL’ and NodeID= (select MsGPNodeID from MsGpNode where Name=’taPoHdr’)

This will make the PO Subtotal field no longer required in SmartConnect. Now you can unmap the field, and the eConnect node will automatically calculate the subtotal for you.

    What table should this be run against for the PO subtotal ?

    UPDATE SmartConnect..[Field] SET Required = 0 WHERE Node = ‘taPoHdr’ AND TechnicalName = ‘SUBTOTAL’

    Cheers and thanks

    This update statement needs to be run in SQL management studio against the SmartConnect database. It makes the subtotal field not required, so you can unmap it in SmartConnect.

    SQL management studio must be used to perform this statement against the SmartConnect database. In SmartConnect, the subtotal field is no longer required, so you can remove it

    To make changes to the SmartConnect database, execute this update statement in SQL management studio. Because of this, the subtotal field may be unmapped in SmartConnect and is no longer necessary.

    We had to also go into Node Builder for the PO Header and uncheck the field as required even after running the script. Wondering if just opening the node builder and removing there without having to run the script would be the same.
