SOAP:1.027 SRT: Serialization / Deserialization failed in ABAP Proxy
<p>I have to create a consumer proxy in SAP, the proxy generation is OK (or no errors were reported), but when i tried yo consume the proxy (SE80), i have the next error:</p>
<p><strong>SOAP:1.027 SRT: Serialization / Deserialization failed</strong></p>
<p><strong>System expected a value for the type g.</strong></p>
<p><a href="https://i.stack.imgur.com/OwGYe.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/OwGYe.png" alt="Error SAP - Customer Service" /></a></p>
<p>If i continue, i have the response, but when i tried to call the customer service in a report, i have the error and i can't continue.
In a report, when i tried yo consume the proxy using this code, i have the same error, and i don't have response:</p>
<pre><code>CREATE OBJECT proxy
  EXPORTING
    logical_port_name = 'LOGICAL_01'.

CALL METHOD proxy-&gt;proccess_check_status_invoice
  EXPORTING
    process_check_status_invoice   = input
  IMPORTING
    process_check_status_invoice_r = output.
</code></pre>
<p>Whow can i solve this error?</p>
<p>Thanks,</p>
