I see this error when generating BI-Publisher reports that return no data. Check your query to verify it returns data. Also check that any bind variables used by the query have appropriate values.
If it is the case where your query returns no data but you'd like to avoid the confusing message you can code around it by adding the following logic in your report template. For this work around to work it assumes you've got BI-Publisher licensing (you can create report queries and report templates through shared components).
In the following example it is assumed that the xml structure has a REGION element. You can substitute the REGION element with whatever element works for your xml structure.
Example XML structure
<?xml version="1.0" encoding="UTF-8" ?>
<ROWSET>
  <ROW>
    <REGION>Central Office</REGION>
    <LOCATION>Materials Management</LOCATION>
    <DIRECTOR>Blow, Joe</DIRECTOR>
    <NOTES />
  </ROW>
  <ROW>
    <REGION>Second Region</REGION>
    <LOCATION>Accounts Payable</LOCATION>
    <DIRECTOR>Blow, Jill</DIRECTOR>
    <NOTES />
  </ROW>
</ROWSET>Add code like the following to your template. The code looks to see if records exist in the xml structure. If records DO NOT EXIST then it will return a pdf with the statement "No Data Found for Specified Search Criteria". Of course if data exists... you'll see that on your report.
<?if: REGION  = ''?>
     No Data Found For Specified Search Criteria
<?end if?>
<?if: REGION != ''?>
    your_data_group_starts
    your report template definition
    your_data_group_ends
<?end if?>
