JCO Timeout for SAP Business Connector 4.7

77 Views

Environment :

Windows 2000, SAP Business Connector (BC) 4.7

General Description :

SAP BC is used to invoke BAPI's in the SAP R/3 system.

Issue :

Some BAPI's are taking some time to return response depending on user load. Need to provide a timeout for RFC calls invoked by SAP BC using JCO.

Following is the entry in the rfc trace log file when BC starts up ...

Questions :

1) Is there a SAP BC configuration parameter for RFC execution timeout ??

2) Any other way of enforcing the RFC time out ??

3) If there is a way to set timeout on JCO.Client.execute method ??

I really appreciate your help !!
