BI XML Publisher rtf template fails when no data in report.
I need to sum (col1) and sum (col2) and subtract. Used syntax <?xdoxslt:sum(col1) - xdoxslt:sum(col2)?> and it worked fine if there is data in report. But it fails when there is no data in report. How can I handle no data in rft template for this field. Please advise.
