3513216 - Received IDOC are trimmed the spaces at the starting of segment field

Sending inbound IDOCs via HTTP, SOAP, or file, found the leading spaces of segment field value got trimmed in ABAP system.

For example, in the xml file:
<E1xxxxxxxxxx SEGMENT="1">
            <FIELD> xxxx</FIELD>
                          ^

But in ABAP system WE02 to check the IDoc's segment, the field showed as xxxx without the leading space.
