Cache

In a report, when the subreport needs to be run more than once, set the property Cache to true. The data of the subreport will be cached in the data buffer. When the subreport is run the next time, the sub-engine will retrieve the data from the data buffer instead of DBMS, and if sublink exists, it will also be calculated in the data buffer, thus improving the engine performance.

When a data buffer is defined in the sub-engine, the data buffer is divided into many pages and records are allocated in the pages. You can use the properties Records per Page and Maximum Page Number to set the number of the records in one page and the maximum number of pages in the data buffer. If enough physical memory is available and you know the total number of records in the subreport, to achieve better performance, you can set Records per Page approximate to the total number of records.

Note: The Cache property will not work in the following cases:

When the parameter is displayed in the Parameters in subreport tab which is contained in the query of the subreport.
When HDS is used by the subreport.
When dynamic query is used by the subreport.
