To speed up high volume report work on calculating results, use data caching .
Caching is applied to the reports containing:
Large data areas or multiple data areas.
Large selection, which exceeds 10 000 elements.
A great number of parameters connected between each other and data sources.
Hyperlinks, formulas, event handlers.
The speed-up is executed on opening the report for viewing.
When adding a cache element an instance of the report with saved calculation results is created. On opening a report the existence of a record in cache is checked. If such a record is found, cached report version is extracted and opened. If the record is not found, the last version of the report is opened from a repository. Regular report instance cache is stored in the repository database.
To cache reports, select the Object Cache item in the regular report context menu in the object navigator. The Object Cache dialog box opens.
The following operations are available on caching:
Caching parameter report creates instances of the report opened with certain values of report parameters. On opening a report with some parameters, the cache is checked for availability of a record corresponding to these parameters. If such a record is found, cached report version is extracted and opened. If no record is found for the specified parameters, the last report version is opened from the repository.
