Clarity

Hi,

We are using Crystal Reports XI v12.3 for Clarity reporting.

One of the reports was modified for a particular business requirement, after which we started getting a 'File I/O error' in the report.

This generally happens when the amount of data retrieved by the report is large.

Report does produce an output window. However, all it contains is the error message "Error in file XXXXX : File I/O error".

Can someone help me identify the root cause of this error?

Can it be a memory issue? Is it some setting in the BO configuration?

Thank you.

Hi All,

Any ideas here for this one?

Thanks!
Chris

Hi Mangesh,

This issue seems to be due to the large number of Data.

Just a guess, If you haven't done these two steps before while installation of BO.

In the Crystal Reports Processing Service section, complete the following fields:
Database Records Read When Previewing or Refreshing (0 for unlimited)
Defines the number of database records that are read when you preview or refresh the database.
Enter 0.
Default: 20000


In the Crystal Reports Cache Service section, complete the following fields:
Maximum Cache Size (KB)
Defines the maximum cache size in kilobytes.
Enter 512200.
Default: 256000
