User (Legacy) Posted July 24, 2004 Report Share Posted July 24, 2004 Greetings, When exporting a chart using the OLAP Extension, I notice the data gets exported as part of the Extensions node of the XML. This occurs even when you use a FileMask setting that excludes data as part of the export. When you import the chart, the data that appears as static. We need to find a way to export a chart that uses the OLAP Extension, saving the snapshot of the layout of the chart (dimensions selected, category bar filters, etc.) and somehow make the data dynamic when the chart is imported. Any ideas? Thanks in advance for your help Wendell Giedeman Six Disciplines Corp. Link to comment Share on other sites More sharing options...
Software FX Posted August 5, 2004 Report Share Posted August 5, 2004 Hi, We have been working on this issue and we feel we are very close to release a new version that would support your scenario. I am posting this to make sure we are on the right track. Some background facts: - When you export a chart we use the file mask which by default includes everything (data, extensions and other settings not relevant for this discussion) - When you export a template we use a builtin file mask that does not include data or extensions. Note that templates are important in this discussion because we use them to support Personalized Charts. - Saving data in an OLAP chart is key because we use this persisted chart on the client side (web scenario) who has no access to the data layer. - We cannot modify what gets saved by default because this would break compatibility with existing apps - When a chart with extensions is read, the previous list of extensions is removed. To support saving OLAP state with no data we are implementing the following a) OLAP will honor the FileMask.Data flag. Note that even if you do not change the MDX statement, just running at a different time may result in different Dimension Levels or Values. In Time Dimensions executing the same statement at the end of a year or the beggining of next year results in different values (1997,1998 against 1997,1998,1999) A new FileMask flag (FileMask.ReuseExtensions) that allows to read the extension list reusing the objects (if the extension is already attached to the chart) In the new scenario you can add ReuseExtensions and remove Data from the FileMask, then you can import this settings chart over a chart that already has the OlapExtension with new data. Note that the order here is CRUCIAL, data should be read first. This solves the Windows Form scenario but not on the Web. We are considering different options to allow personalized charts with OLAP state to be persisted correctly. We would appreciate any feedback you can provide, JC SoftwareFX Support "Wendell G." <wgiedeman@sixdisciplines.com> wrote in message news:fRR1NJZcEHA.3080@webserver3.softwarefx.com... > Greetings, > > When exporting a chart using the OLAP Extension, I notice the data gets > exported as part of the Extensions node of the XML.
