I am running an update import (SB) on matrix items. I am getting an error message "items you have requested in the record have been deleted since you retrieved them". I have looked on suite answers and the only accounting set up I had not populated as the gain/loss account which related to transfer costs being assigned to SKU's at the point of dispatch. I have tried to update the gain loss account on the matrix parent and also on the matrix child as part of the CSV import and I get the same error message. Any suggestions?
