The following information includes common problems that occur with mappings.
Situation When I run an integration, I get an error that a destination field can’t be null.
Solution The default rule for destination fields is If Null Cancel Document. If this is not the desired behavior, change the destination field rule to If Null Use Blank or If Null Use Default. To change this rule, open the Destination Mapping window and select the field that is causing the error. In the lower left corner of the mapping window, change the Rule Property selection from If Null Cancel Document to the appropriate value.
