Crystal Report scheduling error

Hi,

We have a Crystal Report which was developed using SAP ECC source. It was running fine, but from couple of days report is failing with the below error.

"Error in File ~tmp360481b453961a0.rpt: Database Connector Error: 'An error occurred when setting up the system for batch data reception. Please see SAP system and gateway logs for details.' "

We have updated the source and ran the report in designer, but after 40 mins we are getting RFC_Closed error.

We scheduled the report with removing restrictions and Groups even though we are getting same error message.

Environment details:

Business Object 4.0 SP4

Crystal Reports 2011 SP4

SAP ECC
