I have integrated ECC with C4C via CPI.
It works almost right because i.e. i send a few materials by Tcode BD10 it takes too much time but works good. And when i send something like 30 or more materials there is an error like i show in attached image by Tcode WE02 and also takes too much time, like 20 min processing and later the error.
"Problem with SOAP class
Message no. EA390
The SOAP IDoc application could not be started successfully.
The problem occurred in the method call: execute_processing
1023:SRT: Processing error in Internet Communication Framework: ("could not write request to partner")
Inform your system administrator"
In CPI sometimes got error :Error Details Inbound processing in endpoint at /ERP/COD/MATMAS_CFS_MATMAS05 failed with message "Fault:java.net.SocketTimeoutException", caused by "SocketTimeoutException:null"
