@KowsalyaMK This query looks to be generated from a custom report definition, and possibly timing out due to query size; can you confirm? If this is a custom report, you should consult with your DBA for any index recommendations for improving query performance.
There is insufficient detail here - did you check your PegaRULES and PegaRULES-ALERT logs from the node where the report ran?
For a slow report we recommend the following steps
Get tracer w dbQuery option
Take the query to DBA for Explain plan
Take any index advice provided by the DBA.
If you need an in depth investigation please log a support issue via the MSP and provide the INC id here so we can help track it.
