Invalid function when consuming SOAP web service

(0) ShareShare
ReportReport
Posted on by Business Central 95

Hi.
I have a problem to consume a web service made with SOAP in .net with Microsoft Business Central. It does not recognize the functions.
The fact is that I have been using the same web service since Nav 2009 and I have never had problems, but since Business Central (BC14 and BC15), it gives errors.
I discovered that the functions became [External] -> Scope ('Extension') -> Scope ('Cloud') depending on the version, but I've tried everything and it still doesn't work.
The SOAP Services of the service is active.
This is the error you make when calling the web service:

System.Web.Services.Protocols.SoapException: Method "Gfu_ObtUsuarios" is invalid!
en System.Web.Services.Protocols.SoapHttpClientProtocol.ReadResponse(SoapClientMessage message, WebResponse response, Stream responseStream, Boolean asyncCall)
en System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters)
en PasarelaWebServiceDvMobileLogistics.WS_Sailor.WS_MobileLogistic.Gfu_ObtUsuarios(String ps_Usuario, String ps_Password, String ps_IdAndroid, String& ps_xml)
en PasarelaWebServiceDvMobileLogistics.ServicioClientesAndroid.ObtUsuarios(Int32 p_nUsuario, Int32 p_nPassword, String p_strIdAndroid)

And in event viewer it gives this error:

If anyone knew the problem, I would be very grateful, because I have been behind the problem for a long time.
Thanks.

    This appears to be resolved, as explained in this post:  demiliani.com/.../

    by changing the "FunctionVisibility" to external in the globals > funciton > properties of the CU

    RE: Invalid function when consuming SOAP web service

    We have just upgraded to BC 14, and it appears that web services based on code units no longer work.  The XML produced by the web service is not the same as the NAV 2015 version...it's missing several nodes.

    Did Anyone find a solution for this? I am also having a very similar issue and would like to know how this was resolved.

    RE: Invalid function when consuming SOAP web service

    Hi.

    I've added it again but it still fails.

    The web service is mounted on Nav:

    Codeunit  50100  MobileLogistics  WS_MobileLogistic  0  1  dvlogisticbc15.davisa.local:7047/.../WS_MobileLogistic

    And if I click on the link, open the web service:

    <definitions xmlns="schemas.xmlsoap.org/.../" xmlns:tns="urn:microsoft-dynamics-schemas/codeunit/WS_MobileLogistic" targetNamespace="urn:microsoft-dynamics-schemas/codeunit/WS_MobileLogistic">

    <types>

    <schema xmlns="www.w3.org/.../XMLSchema" elementFormDefault="qualified" targetNamespace="urn:microsoft-dynamics-schemas/codeunit/WS_MobileLogistic">

    <element name="gfu_User">

    <complexType>

    <sequence>

    <element minOccurs="1" maxOccurs="1" name="user" type="string"/>

    </sequence>

    </complexType>

    </element>

    <element name="gfu_User_Result">

    <complexType>

    <sequence>

    <element minOccurs="1" maxOccurs="1" name="return_value" type="boolean"/>

    </sequence>

    </complexType>

    </element>

    </schema>

    </types>

    <message name="gfu_User">

    <part name="parameters" element="tns:gfu_User"/>

    </message>

    <message name="gfu_User_Result">

    <part name="parameters" element="tns:gfu_User_Result"/>

    </message>

    <portType name="WS_MobileLogistic_Port">

    <operation name="gfu_User">

    <input name="gfu_User" message="tns:gfu_User"/>

    <output name="gfu_User_Result" message="tns:gfu_User_Result"/>

    </operation>

    </portType>

    <binding name="WS_MobileLogistic_Binding" type="tns:WS_MobileLogistic_Port">

    <binding xmlns="schemas.xmlsoap.org/.../" transport="schemas.xmlsoap.org/.../>

    <operation name="gfu_User">

    <operation xmlns="schemas.xmlsoap.org/.../" soapAction="urn:microsoft-dynamics-schemas/codeunit/WS_MobileLogistic:gfu_User" style="document"/>

    <input name="gfu_User">

    <body xmlns="schemas.xmlsoap.org/.../" use="literal"/>

    </input>

    <output name="gfu_User_Result">

    <body xmlns="schemas.xmlsoap.org/.../" use="literal"/>

    </output>

    </operation>

    </binding>

    <service name="WS_MobileLogistic">

    <port name="WS_MobileLogistic_Port" binding="tns:WS_MobileLogistic_Binding">

    <address xmlns="schemas.xmlsoap.org/.../" location="dvlogisticbc15.davisa.local:7047/.../>

    </port>

    </service>

    </definitions>

    The problem is calling that function from the web service.

    Is it because the web service is made in visual studio 2012 and may it be old or has the access url changed in the version of Business central 15?

    Yes, this method is accessible from the outside. Can you try to re-add the web service reference in Visual Studio?

    RE: Invalid function when consuming SOAP web service

    I think that there has to be the problem, that something must be defined in the function to be externally accessible.

    It is a simple codeunit that only returns the true value if it is entered:

    codeunit 50100 "MobileLogistics"

    {

       trigger OnRun()

       begin

       end;

       procedure gfu_Prueba(Usuario: Text[30]): Boolean

       begin

           exit(true);

       end;

    }

    I understand that if nothing is put before the show, it is public.

    What page and method are you trying to call? How is the function you're calling defined in D365BC? Public or not?

    Hi Stefano. Thanks for answering.

    The ultimate goal of the web service is to link data from a PDA with Navision through an application made in .net. It has always worked well for me with previous versions, but not with the central business extensions.

    I discovered in version BC14 that the functions had to be set as external, but in version BC15 that has disappeared and the function defined as [Scope ('Cloud')] is supposed to be, but it does not work. It is as if I find the function I call or because it is in an extension or because I cannot access it externally.

    Greetings and thank you.

    SOAP web services works without problems. What is the object exposed as web service? Please give more details about your scenario.
