Error in RFC Sender Channel - maximum size of requests for one LUW has been reached (1)

[Former Member]

Hi Everyone,

We are facing a issue in the SM58 of ECC system and the same reflects in PI RFC Sender channels also. The error message is as below.

Error in processing caused by: com.sap.aii.adapter.rfc.core.server.RfcServerException: maximum size of requests for one LUW has been reached (1). handling of request for tRFC (TID: 0A1391F71784547BF7C41F83) not possible (server: RfcServer[CC_RFCSender]

The Program ID maintained in ECC and PI channel are the same. We could see messages get processed successfully but few messages have this issue.

The Parameters maintained in the RFC sender channels are as below

Intial Connection : 1

Maximum Connections : 50

Kindly let me know on how to solve this issue.

Regards,

Hi GB,

I have referred these posts before but none has a solid solution. In one post it is mentioned to have RFC Wrapper but i am not sure how to achieve this.
