2966373 - Timeout error on Master Data and Org. Assignment replication from SF EC to ERP


You are using the CPI process below to replicate Master Data and Org. Assignment data from SF EC to ERP:

  • Replicate Employee Master Data and Org. Assignments from SAP SuccessFactors Employee Central to SAP ERP or SAP S4HANA

And the process is randomly failing with an error similar to this one below:

Inbound processing in endpoint at /EC_to_ERP_Master_Data_And_Org_Query failed with message "Fault:Sequential processing failed for number 1. Exchange[xxxxx]. Caused by: [org.apache.cxf.interceptor.Fault - Could not send Message.]", caused by "SocketTimeoutException:connect timed out (local port xxxxx to address xxxxx (xxxxx), remote port xxxxx to address xxxxx)"

Image/data in this KBA is from SAP internal systems, sample data, or demo systems. Any resemblance to real data is purely coincidental.

  • Cloud Platform Integration (CPI)


Decrease the page size and increase the timeout parameters of your process, this way it can process less data in more time, avoiding timeouts.

In the configuration of the process on CPI, go to "Receiver" tab and select Employee_Central receiver. Set the parameters as below:

  • Page Size = 200
  • Timeout (in min) = 10

After this, select the receiver ERP_Response and change its Timeout parameter to 600000:

This should be enough to avoid timeout errors. 

If you still face the issue even after these changes, you can try decreasing the page size and increasing the timeout a bit more and testing. You would need to tune these parameters according to your business scenario.
