in BI 4.1 where should we change the default LO rows limit parameter 512?

Hi,

We recently migrated to BI 4.1 . what we found later when we open dashboards or publish new dashboards to portal, data getting truncated at 512 rows.

I am not able to locate Live office config file under DSWS folder which used to be there in lower versions. we changed the row limit in excel options going file --> preferences on xcelsius. on BO/Tomcat folder please suggest the file path where we need to change this default row parameter
