I am building a simple BIRT report using an XML data source. However, I had to use 3 different views (3 cross-tabs) of the same data on the same report. While running the report, I noticed that BIRT was firing multiple calls to fetch the XML file (hosted in a web-server). I have tried fiddling with the settings tab of the edit screen of the data set. But the behavior does not seem to change. I would really appreciate if anybody can help me identify what is going on. Also how do I ensure that a data-set is fetched only once during the rendering of a report

Thanks in advance

    The data set should only be fetched 1 time. Do you have three data sets for the report, each one representing a different sub-set of fields? If so that would explain the three separate fetches.

    Can you create a single large data set that satisfies all the cross-tabs and then use run-time filters to produce the individual sub-sets you need? Another option would be to consume your XML via a POJO and leverage it in the BIRT report as a scripted data set. This would certainly give you the control you are looking for.

    If you are interested in looking at building a scripted data set, have a lok here for a bit of backaground. accessing parameters when writing a scripted BIRT data source in java

    Good Luck!
