Hi guys, Hope that anyone encountered this issue, as I'm guessing not much people are working with this API. I created an outbound campaign using the API, and I tried to import records to it.  I was able to do that, but I had an issue, when I'm trying to load records when Phone02 is empty, it won't let me import those records. The output I'm getting is:   <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <apiErrors> <apiError> <errorData>fileContent</errorData> <errorDetail xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="bulkCsvErrorDetail"> <column>5</column> <error> <errorData>Phone02</errorData> <errorMessage>The format of this field is incorrect. Valid characters are 0-9, #, and *.</errorMessage> <errorType>invalidInput.invalidChars</errorType> </error> <line>2</line> </errorDetail> <errorType>invalidInput.bulk.invalidFileContent</errorType> </apiError> </apiErrors>   This is how I'm trying to import: <import> <fileContent> <![CDATA[ AccountNumber,FirstName,LastName,Phone01,Phone02,TimeZoneBias,DstObserved LwxbZcYdVQGpyYDUYu4WRK3QQVSe4,Name,LastName,12126186597,,, ]]> </fileContent> <delimiter>,</delimiter> </import>   Only when I'm inserting a value in Phone02 it will import the record via API. Now I understand that when creating an outbound campaign using the API, it also generates automatically an import rule for it. And after viewing a table called Import_Rule_Clause, I see that there's only one record generated for this specific campaign and it is Phone01, so I'm guessing because it has no Phone02 in there that is stating 'NullEnabled' (field) = 'Y', so the API won't be able to bypass that.  Of course I will not add manually a record for this campaign with Phone02 to the above table, as it'll may crash my system as it is not allowed.   Is there something I can do here?   Thanks!   Slavik Bialik.   ...
