Time Out Error when using OData Connection Service

[former_member716880]

Hello. I have a question about OData Connection between SAP and Mendix by POST method.

I am using Purchase Order API which is offered by SAP and trying to create objects by using OData service.
The Mendix application is deployed on SAP cloud platform.
This app connects to S4 HANA (on premise) through Cloud Connector.

Successfully, I can get list of Purchase Order.(GET method)
However, When I tried creating new Purchase Order, An error occurred.(POST method)

java.net.SocketTimeoutException
Read timed out
com.mendix.systemwideinterfaces.MendixRuntimeException: java.net.SocketTimeoutException: Read timed out
at com.mendix.basis.actionmanagement.ActionManagerBase.executeSync(ActionManagerBase.java:156)...

Actually, I found that I created new Purchase Order, but Socket timeout error message is displayed on a screen.

※I checked error log on SAP GUI, but SAP didn't throw any errors.

Is this issue caused by Mendix or SCP?

any help would be appreciated!
