Back to Main Report-Web Elements

Question

Hi
Based on the Web Elements prompts selection on the report we are displaying graph and table output which is an aggregarte information. On the same report, we are also using opendocument function called DetailReport to show detail information which shows the data in different report. On the other report we have kept BacktoMainReport using open document to show the Main report with graph and table output .
Just wanted to know when we hitting on backtomain report with opendocument function, right now we are using query to go back to MainReport. Without doing that, is there any option to show the MainReport without generating query again .. i mean Report storing the information in cache,just showing that directly.
Thanks

Answer 1

hi Mufiza,
if you are using cr2008 you can do this by saving a report to your enterprise system with the File > Save Data With Report option in conjunction with using the Saved Data Record Selection Formula. then every hit to that report will hit the data cache stored in the report as opposed to hitting the database.
if you are using a lower version, the only thing you can do is cache your reports using the enterprise server settings. however, if you have parameter / prompts on the report in question, then this can become difficult. you can only hit a cached instance if that parameter / prompt combination has already been viewed within the caching time period, otherwise a database hit will be done.
again, this is much easier to do with cr2008.
also, you don't necessarily have to use opendocument linking either...to create a "back to main report" between 2 reports, here's a really easy way that uses Report Part linking:
1) open up your 2 reports in the crystal reports designer (assuming that both are already stored in your enterprise system)
2) on your "main report" Insert a Text Object on to the Report Header...leave it blank
3) right click on the new Text Object and choose Copy
4) on your 2nd report, Insert a Text Object on the Report Header and type in "Back to Main Report"
5) right click on this new Text Object and choose Format Text > Hyperlink > Another Report Object and then Paste...this will paste the Report Part info from the Main Report into this 2nd report
after saving the reports you can test the hyperlink in your enterprise viewer. for more info on Report Park linking see your online help in the Crystal Reports designer.
cheers,
