Crystal Report : “File is too large for attachment” Error

问题

I am new for crystal report server. Here I'm explaining error details.

I'm using SAP Business Objects CMC for report generation for my application. Below is the version details in image.

When I try to generate report file with more than 1MB of file size it is throwing below error.

Error 

The viewer could not process an event. 1c84865dce535c5.pdf File is too large for attachment. [] ---- Error code:0 [CRWEB00000119] 

So, I went to following location to check the maximumUploadFileSize.

1. C:\Program Files (x86)\SAP BusinessObjects\tomcat\webapps\dswsbobje\WEB-INF\classes\dsws.properties

2. C:\Program Files (x86)\SAP BusinessObjects\SAP BusinessObjects Enterprise XI 4.0\warfiles\webapps\dswsbobje\WEB-INF\classes\dsws.properties

3. C:\Program Files (x86)\SAP BusinessObjects\SAP BusinessObjects Enterprise XI 4.0\java\pjs\container\work\<ServerName>.WebApplicationContainerServer\businessobjects\dswsbobje\WEB-INF\classes\dsws.properties

#Security measure to limit total upload file size

maximumUploadFileSize = 10485760

It is setted to 10485760 (10 MB), As per my understanding this is default size from this Reference Document.

So, if it is supporting upto 10 MB why it is throwing error when report file exceed 1MB?

And I tried to increase the size by multiple's of 10, meaning 104857600 (100 MB) in all this files, and restarted the server. But with out success, after restarting the server the modified value in third file is again setting to old value (10485760). Please help me in this.

Is there any way to increase maximumUploadFileSize through administrator console?

Please drop your comments, if you have any questions/doubts regarding this.

This issue can be resolved by following steps.

Actually this issue is related to number of records which are trying to generate as report in crystal report server. The default record data size limit is 20,000. By changing the limit into 0 (for Unlimited) we can able to resolve this issue.

Follow below steps to do this setting changes:

1. Log onto the CMC
2. Go to Servers in the drop-down menu
3. Expand Service Categories
4. Select Crystal Reports Services
5. In the right window will be listed the currently running services, find CrystalReports2013ProcessingServer under Description.
6. Double click on that, it will redirect to Properties page.
7. Set the value 0 for "Database Records Read When Previewing or Refreshing (0 for unlimited)".
8. Click Save & Close.
9. Restart CrystalReports2013ProcessingServer.

Now try to generate the large data pdf file, it should work fine.
