How can I change the timeout parameter?

You have exceeded the MDM ABAP API Communication timeout and recieved an error message, however your process does indeed take longer than the default time.

The timeout parameter is set and controlled by the ABAP side of the communication. The default value of the timeout is 30000 milliseconds. The timeout parameter is controlled by the ABAP Profile Parameter mdm/network_timeout. For more details see OSS Note 968804.
